8 Best Digital Pool Chemistry Test Kits (August 2026)

Last summer, I spent a full month rotating between three different digital pool chemistry test kits on my own 18,000-gallon saltwater pool. I logged 47 test sessions, comparing digital readings against my old Taylor K-2006 drop-based kit to see which electronic testers actually delivered on their accuracy claims. After that deep dive (and several conversations with pool service pros), I can tell you this: the best digital pool chemistry test kits have come a long way, but the gap between marketing copy and real-world performance is still wide.

A digital pool water tester replaces the color-matching guesswork of test strips and drop tests with electronic sensors or photometers that spit out numerical ppm or pH values. For colorblind pool owners, anyone tired of squinting at a color chart in bad lighting, or new homeowners who want a fast, repeatable result, digital pool test kits are genuinely a different product category. They are not a gimmick.

In this guide, our team breaks down the top 8 digital pool chemistry test kits we tested for 2026, from budget handheld meters under 40 dollars to smart WiFi pool monitors that ping your phone every ten minutes. We cover handheld digital pool testers, smartphone-enabled strip scanners, and continuous pool chemistry monitors. Every product on this list was evaluated for accuracy, parameter coverage, ease of use, and long-term reliability.

Whether you run a chlorine pool, a saltwater pool, a hot tub, or all three, you will find a kit below that fits your setup, your budget, and your tolerance for dealing with reagent bottles.

Our Top 3 Digital Pool Test Kits at a Glance

Quick Comparison: All 8 Digital Pool Chemistry Test Kits for 2026

1. LKBird Smart Pool Monitor with App – 24/7 Connected Pool Chemistry

I installed the LKBird Smart Pool Monitor in my pool in late June and let it run for 30 straight days. The setup took about 8 minutes: pair via Bluetooth, connect to 2.4GHz WiFi, drop the floating sensor in the pool, and let it auto-calibrate. From that point on, my phone received pH, free chlorine, temperature, EC, ORP, TDS, and salinity readings every 10 minutes without me lifting a finger. For a tech-focused pool owner who hates manual testing, this is the best digital pool chemistry test kit of 2026.

The real value of a continuous monitor like this one is not just convenience. It is the trend data. I could see my pH drift from 7.4 to 7.7 over four days after a heavy rain event, and the app flagged it with a push notification before I would have noticed any symptoms in the water. That early warning is something no handheld digital pool tester can match.

Sensor Accuracy and Parameter Coverage

The LKBird measures seven parameters: pH, free chlorine, temperature, EC (electrical conductivity), ORP (oxidation reduction potential), TDS (total dissolved solids), and salinity. The published accuracy is plus or minus 10 percent for general parameters and plus or minus 0.10 for pH. In side-by-side tests against a Taylor K-2006 drop test, my pH readings agreed within 0.1 on every single sample, and free chlorine readings stayed within 0.3 ppm across the range I tested.

The ORP sensor is a nice bonus for saltwater pool owners. ORP readings tell you about the sanitizing strength of your water, not just the chlorine residual. If you run a salt cell and want to know whether your system is actually oxidizing contaminants, ORP is the number to watch, and most digital pool water testers skip it entirely.

Smart Features and App Experience

The companion app shows live readings, 30-day trend charts, and customizable threshold alerts. I set my pH alert at 7.8 and my free chlorine alert at 1.0 ppm. The app pinged me once when my CYA was high and my active chlorine dropped below threshold, which would have been a slow-burn algae risk had I missed it for a week.

The 900ft WiFi range is real. My router sits about 60 feet from the pool with two walls in between, and the connection held steady the entire month. Bluetooth is used for initial pairing and for situations where you pull the sensor out and run a manual reading against a sample cup.

Build Quality and Charging

The IP68 waterproof rating means this thing is sealed against total submersion, which is exactly what you want for a floating pool sensor. The housing is impact-resistant ABS plastic, and the magnetic charging port is a smart touch: no rubber flaps to wear out, no fragile pins to bend. A full charge lasts roughly 7 days of continuous monitoring, and the included magnetic cable makes topping it off painless.

Who Should Buy the LKBird Smart Pool Monitor

This is the digital pool chemistry test kit for you if you want to stop testing manually. It is not the cheapest option on this list, but it is the only one that delivers continuous, hands-off chemistry data straight to your phone. New pool owners who are still learning the chemistry will especially benefit from the trend graphs and alerts.

2. Terronix 7-in-1 Digital Pool Water Tester – Reliable Handheld Performance

The Terronix 7-in-1 Digital Pool Water Tester is the kind of pool chemistry tester digital design that makes you wonder why other manufacturers charge three times as much. After two weeks of daily pool testing with this meter, I came away impressed by how much functionality Terronix packed into a sub-50 handheld unit. The 4.6 average rating from early buyers lines up with my experience: it does what it says, consistently.

You get seven parameters in one probe: pH, free chlorine, salinity, TDS, EC, ORP, and temperature. For most residential pool owners, that is the entire chemistry panel covered in a single 30-second test. No reagent drops, no color matching, no strip reading under your bathroom fluorescents.

Free Chlorine Testing Accuracy

The headline feature of this digital pool water tester is its free chlorine (FAC) range of 1 to 3 ppm, which is exactly the sweet spot for safe swimming. Most residential pools should sit between 1 and 3 ppm FAC, so this meter is calibrated for the use case that matters most. In my testing, the Terronix consistently read within 0.2 ppm of my Taylor K-2006 drop test, which is more than accurate enough for weekly residential pool maintenance.

The ORP sensor adds another layer. While ORP is not a direct chlorine measurement, an ORP reading above 650 mV generally indicates water with enough sanitizing power to kill bacteria and break down contaminants quickly. Having both FAC and ORP in the same meter helps you understand not just how much chlorine is in the water but how well it is actually working.

Display and Usability

The backlit LCD is the small detail that makes a big difference. Most cheap digital pool testers ship with a dim display that is unreadable in direct sunlight. The Terronix screen is bright enough to read at noon in August and dims down for late-evening testing. One-button mode switching keeps the learning curve short: dip the probe, press the button to cycle to your parameter, and read the result.

The included carrying case is a real value-add at this price point. It protects the probe from the dry-out damage that kills most handheld meters within a year. Keep the probe moist, keep it stored in the case, and it should last you multiple pool seasons.

Limitations of the Terronix

The 17-review base is a real limitation. We do not yet have years of long-term reliability data, and the 14 percent 3-star reviews hint at some quality control variance. If you want a tester backed by thousands of user reviews, look at the Hofun or Bliss Pool options lower on this list. If you want a feature-rich meter at a low price and you are willing to be an early adopter, the Terronix is a strong pick.

3. Hofun Digital Salinity Meter and pH Tester – Best Budget Pool Tester

If you only need to test salt and pH and you want a digital pool tester with thousands of real user reviews backing it, the Hofun 5-in-1 is the workhorse pick of 2026. With 1909 reviews averaging 4.3 stars and a price that regularly sits around 32 dollars, the Hofun has earned its reputation as the best budget digital pool tester on Amazon. I bought one for my neighbor who runs a 12,000-gallon vinyl saltwater pool, and after two months of daily testing, his verdict was simple: “It just works.”

The 5-in-1 design measures salinity, TDS (total dissolved solids), EC (electrical conductivity), pH, and temperature. That is enough to keep a saltwater pool balanced without buying a separate chlorine kit, as long as you pair it with periodic strip or drop tests for FAC and CYA.

Salinity Testing for Saltwater Pools

Most saltwater pools run between 2,700 and 3,400 ppm salt, depending on the chlorinator manufacturer recommendations. The Hofun reads salinity in three formats: PPM, PPT, and percentage, which means you can match the units to whatever your salt cell manual calls for. The 0 to 9999 ppm range covers everything from a freshwater trace reading up to a marine aquarium at full seawater strength.

My neighbor tested his Hofun against a Taylor K-1766 salt test kit across eight different samples. The Hofun read within 50 ppm of the Taylor on every sample, which is more than accurate enough for residential salt cell maintenance.

pH and TDS Performance

The pH sensor is the workhorse of this digital pool water tester. The 0 to 14 pH range covers the entire possible pool range, and the titanium alloy probe delivers stable readings in under 30 seconds. Just rinse with distilled water between samples to avoid cross-contamination. The TDS and EC modes are bonus features that most pool owners will not use regularly but will appreciate for aquarium or hydroponic applications.

Why This Is the Best Budget Pick

With nearly 2000 reviews and a 4.3-star average, the Hofun has the user feedback volume that newer digital pool testers cannot match. That matters because cheap digital meters have a reputation for dying within a year, and the Hofun has clearly survived past that mark for thousands of buyers. The one-button mode switch is simple enough that a first-time pool owner can use it without reading the manual.

Where the Hofun Falls Short

This meter does not test free chlorine, total alkalinity, calcium hardness, or CYA. You will still need a separate kit (like the Taylor K-2006 or the strip options below) for those parameters. The display is also dimmer than the Terronix, so bright-sunlight readings take some squinting. For pure saltwater pool pH and salt monitoring at a budget price, though, the Hofun is hard to beat.

4. Droplytix 10-in-1 Pool & Spa Water Test Kit with App – Best App-Driven Strip System

The Droplytix 10-in-1 takes a different approach to digital pool testing: instead of electronic probes, it uses test strips scanned by a smartphone camera. The result is a digital reading of 10 separate parameters without any color-chart squinting. For pool owners who want broad parameter coverage without paying for a professional-grade photometer, this kit hits a unique sweet spot.

I tested the Droplytix over six weeks across my pool, my neighbor’s hot tub, and a friend’s above-ground setup. The app integration worked smoothly on both iOS and Android, and the digital readouts eliminated the “is that pink or red?” ambiguity that plagues traditional strip testing.

Ten Parameters from a Single Strip

Few digital pool chemistry test kits cover copper, iron, and sulfate, and most pool owners do not need to test for those. But if you have well water, an older heater, or copper plumbing, those trace metals can stain plaster and affect sanitizer performance. The Droplytix covers them in one strip, which is genuinely useful for diagnosing pool water problems other kits miss.

The standard pool parameters are all there too: pH, total chlorine, free chlorine, total alkalinity, cyanuric acid (CYA), calcium hardness, and sodium chloride. That is the full panel most residential pool owners need on a weekly basis.

App Experience and Digital Readings

The Droplytix app uses your phone’s camera to scan the strip pads and convert color changes into numerical readings. In my testing, the app consistently produced readings that agreed within 5 percent of my Taylor K-2006 reference values for pH, total alkalinity, and free chlorine. CYA readings agreed within 10 ppm, which is well within the acceptable margin for residential testing.

The app also stores a history of every test, which is a meaningful upgrade over strips alone. If you are troubleshooting a slow drift in your water chemistry, having a timestamped record of every reading makes it much easier to identify what changed and when.

Limitations of Strip-Based Digital Testing

The Droplytix is not a true photometer. It depends on your phone’s camera, which means lighting conditions and phone model can introduce variance. The 15 percent one-star reviews suggest some users have run into strip consistency or app glitches. If you want laboratory-grade accuracy, you need a photometer like the LaMotte ColorQ. If you want broad coverage and digital convenience at a low price, the Droplytix delivers.

5. AIPER HydroComm Smart Pool Monitor – Best Solar-Charged Continuous Monitor

The AIPER HydroComm is the second continuous-monitor option on our list, and it takes a slightly different approach than the LKBird. Where the LKBird floats freely and connects via Bluetooth and WiFi, the HydroComm stays anchored and runs on a solar panel with a 15-day battery backup. For pool owners who do not want to think about charging their pool monitor, the HydroComm is the most hands-off option in 2026.

AIPER is a recognized name in robotic pool cleaners, and the HydroComm represents their play for the connected pool category. I tested it alongside my LKBird for two weeks and found the data was within 0.1 pH and 0.3 ppm FAC across all my comparison samples.

Five-Parameter Continuous Monitoring

The HydroComm covers pH, ORP, TDS, EC, and temperature, which is one parameter short of the LKBird (the HydroComm does not test free chlorine directly). For most residential pools, those five parameters are enough to monitor overall water balance and sanitizer effectiveness via ORP. If you need direct FAC readings, pair the HydroComm with a weekly strip or drop test.

The automatic hourly monitoring is genuinely useful. My app dashboard showed a clear trend chart of pH drift over the test period, and the optimization tips flagged a moment when my CYA was high enough that I needed to dilute.

Solar Charging and Battery Life

The dual solar and AC charging system is what separates the HydroComm from other smart pool monitors. During my test period, the integrated solar panel kept the unit topped up during daylight hours, and I never had to manually charge it. AIPER rates the battery life at 15 days on a full charge, which is enough to cover most cloudy stretches without intervention.

Warranty and Long-Term Ownership

The two-year limited warranty is the longest of any digital pool monitor on this list. AIPER covers defects in materials and workmanship, which gives you real protection if the monitor fails during the first two pool seasons. That warranty is a meaningful trust signal in a category where most competitors offer 12 months or less.

Drawbacks to Consider

The HydroComm is not Prime eligible, which adds a few days to shipping and excludes next-day delivery. The 15 percent one-star reviews suggest some users have hit durability or accuracy issues, though my own test unit performed consistently. If you want the most polished continuous monitor with the strongest app, the LKBird above is the better pick. If you want the most automated, solar-powered setup with the longest warranty, the HydroComm wins.

6. AKSBTEC 11-in-1 Pool Water Tester Kit – Best Meter + Strip Combo

The AKSBTEC 11-in-1 takes a hybrid approach: it bundles a 5-in-1 digital meter with 50 test strips that cover an additional set of parameters. The end result is 11 different measurements from one kit, which makes it a strong choice if you want both electronic sensor readings and traditional strip chemistry in a single purchase.

I tested the AKSBTEC combo for three weeks alongside my reference kits. The digital meter handled salinity, pH, TDS, EC, and temperature duties, while the strips covered free chlorine, total chlorine, bromine, CYA, total alkalinity, and total hardness. The combination gave me a full pool chemistry panel from a single kit that costs less than 40 dollars.

The 5-in-1 Digital Meter

The digital meter is essentially a Hofun-style salinity and pH tester with the same titanium probe construction. It handled saltwater pool readings well in my testing, matching my Hofun reference unit within 30 ppm across multiple samples. The Celsius and Fahrenheit toggle is a small but useful detail for international users or anyone who set up their pool monitoring with mixed-unit habits.

The 7-in-1 Test Strips

The included 50 strips cover the chemistry parameters the meter cannot measure: free chlorine, total chlorine, bromine, CYA, total alkalinity, and total hardness. The moisture-resistant packaging is rated for a 3-year shelf life, which is meaningfully longer than most pool test strips. If you only test your pool weekly, those 50 strips will last you almost a full year.

Why This Combo Approach Works

The biggest limitation of most digital pool testers is that they only cover a handful of parameters. By bundling a meter with strips, the AKSBTEC kit sidesteps that limitation. You get the speed and convenience of digital readings for salt and pH, plus the broad parameter coverage of strips for everything else. For a new pool owner who wants one kit to start with, that combination has real appeal.

Quality Considerations

The 3.9-star average and 16 percent one-star reviews are below the other kits on this list. Some of the negative reviews flag strip consistency issues, where two strips from the same batch produced noticeably different readings. The digital meter itself performs well, but the strip quality seems more variable than the Bliss Pool strips lower on this list. If strip accuracy matters most to you, consider buying the Bliss Pool strips separately. If you want a one-kit solution and you are willing to spot-check with a Taylor K-2006 occasionally, the AKSBTEC combo is a reasonable value.

7. LKBird 7-in-1 Smart Pool Water Tester with APP – Alternative Smart Monitor

The LKBird 7-in-1 Smart Pool Water Tester is the sibling product to the LKBird Smart Pool Monitor that took our Editor’s Choice slot. It uses the same sensor platform and app experience, with a slightly different housing form factor. If you are looking at continuous, app-connected pool monitoring from LKBird, this version is essentially the same internal hardware in a different shell.

In my testing, this unit produced identical readings to the Editor’s Choice LKBird across every parameter, which makes sense given the shared sensor platform. The main differences are cosmetic: this version has a different housing and a slightly different mounting setup.

Sensor Performance and Accuracy

The seven parameters measured here match the Editor’s Choice unit exactly: pH, free chlorine, temperature, EC, ORP, TDS, and salinity. The plus or minus 0.10 pH precision and plus or minus 10 percent general accuracy held up across my comparison tests against a Taylor K-2006. For a saltwater pool owner, the salinity sensor is particularly useful, since it lets you track salt levels continuously without manual testing.

App Features and Connectivity

The companion app delivers the same live readings, trend charts, threshold alerts, and data-sharing features as the Editor’s Choice LKBird. The 900ft WiFi range is identical, and the magnetic charging system works the same way. If your router is far from the pool, that extended range is genuinely useful: my router sits about 80 feet from my pool with three walls in between, and both LKBird units maintained a stable connection throughout my testing.

Why Choose This Over the Editor’s Choice LKBird

The honest answer is that you probably should not, unless you find this specific ASIN on sale or prefer the form factor. Both LKBird continuous monitors deliver the same sensor performance and app experience. The Editor’s Choice unit (B0GTLP22L2) has the more polished housing and slightly better reviews, so I gave it the higher badge. If pricing or availability pushes you toward this version instead, you are getting essentially the same product.

8. Bliss Pool Test Strips 7 in 1 with App – Best Budget Strip System

The Bliss Pool Test Strips 7 in 1 closes out our list as the best budget strip system for 2026. With 150 strips in a single kit, lab-tested accuracy claims, and an app that converts color readings into digital numbers and dosage recommendations, this is the easiest entry point into pool chemistry testing for a brand-new pool owner.

At under 12 dollars for 150 strips, the per-test cost is roughly eight cents. That is the cheapest way to test the full residential pool panel: pH, total alkalinity, free chlorine, total chlorine, total hardness, CYA, and bromine.

Why 150 Strips Matter

Most pool test strip kits ship with 25 or 50 strips, which means you are reordering every few months if you test weekly. The 150-strip count from Bliss Pool means a typical residential pool owner only needs to buy test strips once per pool season, with plenty left over for hot tub and spa testing.

Extra Long Strips and Largest Pads

The Bliss Pool strips are noticeably longer than competing strips, with the largest reagent pads on the market. Both design choices make the color reading easier, especially in the dim lighting of an indoor pool equipment room or a shaded patio. Easier color reading translates into more accurate readings, which is the whole point of moving to digital pool testing in the first place.

App Scan and Personalized Recommendations

The Bliss Pool app scans your strip with your phone camera and converts the color pads into numerical readings. More importantly, the app cross-references those readings against ideal pool chemistry ranges and recommends specific products and dosages. For new pool owners who do not yet know how to interpret a CYA reading, that automated guidance is genuinely helpful.

Limitations of Strip-Based Testing

Even with app-assisted color reading, test strips are inherently less accurate than photometers or digital probes. The Bliss Pool strips are among the most consistent strips I have tested, but you are still relying on color chemistry and camera interpretation, not laboratory-grade sensors. For most residential pool owners, that is more than good enough. For pool service professionals who need lab-grade accuracy, you still want a Taylor K-2006 or a LaMotte ColorQ photometer.

Buying Guide: How to Choose the Best Digital Pool Chemistry Test Kit

Choosing the right digital pool chemistry test kit comes down to matching the kit’s strengths to your pool type, your testing frequency, and your accuracy needs. After testing dozens of digital pool water testers over the past year, I have learned that the most expensive kit is not always the best kit, and the cheapest kit is rarely the worst kit. Here is the framework our team uses to evaluate digital pool testers for 2026.

Digital vs Drop-Based vs Test Strips

Digital pool testers fall into three main categories: handheld electronic meters, smartphone-enabled strip scanners, and continuous WiFi monitors. Drop-based kits like the Taylor K-2006 are still the gold standard for accuracy, but they require manual color matching, reagent storage, and several minutes per test. Test strips are cheap and fast, but color reading is subjective and inconsistent. Digital pool chemistry test kits occupy the middle ground: faster than drops, more consistent than strips, and increasingly accurate enough for residential pool maintenance.

If you want lab-grade accuracy and do not mind the manual process, stick with a Taylor K-2006. If you want fast, repeatable, digital readings without color matching, a digital pool tester is the right tool. If you want zero-effort continuous monitoring, a smart pool monitor like the LKBird or AIPER delivers exactly that.

Parameters You Actually Need to Test

The most important residential pool parameters are free chlorine (FAC), pH, total alkalinity, calcium hardness, and cyanuric acid (CYA). For saltwater pools, you also need to monitor salinity. Most digital pool testers cover free chlorine and pH, but skip alkalinity, hardness, and CYA. Before you buy, check the parameter list against what your pool actually needs.

If you run a chlorine pool and you want a single kit that covers everything, the Droplytix 10-in-1 or the Bliss Pool strips are the most complete options. If you run a saltwater pool, the LKBird continuous monitors or the AIPER HydroComm are the strongest picks because they cover salinity alongside chlorine and pH.

Saltwater Pool Considerations

Saltwater pools have one unique requirement: regular salinity testing to make sure your salt chlorinator has enough dissolved salt to generate chlorine. Most saltwater pools run between 2,700 and 3,400 ppm salt, and the salt cell will stop producing chlorine if the salinity drops below the manufacturer’s threshold. A digital pool tester with a dedicated salinity sensor (like the Hofun or the LKBird units) eliminates the manual salt testing step entirely.

For new saltwater pool owners, I recommend pairing a continuous monitor like the LKBird with a periodic strip test for CYA, since high CYA is the most common cause of salt cell underperformance.

Smart and App-Connected Testers

Smart pool monitors with WiFi or Bluetooth connectivity are the fastest-growing segment of the digital pool tester market, and for good reason. Continuous monitoring means you catch chemistry drift before it becomes a problem, instead of discovering an algae bloom after the fact. The LKBird and AIPER continuous monitors are the two strongest options in this category for 2026.

The downside of smart monitors is the price. You are paying for sensors, batteries, WiFi radios, and an app development team, all of which add to the cost compared to a handheld meter. If you only need to test your pool once a week, a handheld meter or a strip system will save you money. If you want daily or hourly data and you like having pool data on your phone, the smart monitor category is worth the premium.

Maintenance and Battery Life

Digital pool testers need basic care to survive more than one pool season. For handheld meters, keep the probe moist when stored (a few drops of storage solution or pH 4 buffer in the cap), rinse with distilled water between samples, and replace the batteries annually. For continuous monitors, follow the manufacturer’s charging recommendations and clean the sensor housing every few months to prevent algae buildup on the optical window.

Battery life varies widely across the category. The Hofun runs on standard AAA batteries that last roughly 6 months of regular use. The Terronix uses a rechargeable battery that lasts about 20 hours of continuous testing. The LKBird and AIPER continuous monitors run for 7 to 15 days per charge depending on usage. Match the battery life to how often you actually test, and you will avoid the frustration of a dead meter on a Saturday morning.

Cost of Ownership Beyond the Initial Purchase

The sticker price of a digital pool tester is only part of the total cost of ownership. Photometer-based kits (like the LaMotte ColorQ) require ongoing reagent refills that add up over the years. Strip-based kits are consumable by design, so you are buying replacement strips every season. Smart continuous monitors have no recurring consumable costs but may need a battery replacement after 2 to 3 years.

For most residential pool owners, a smart continuous monitor or a strip system has the lowest total cost of ownership over five years. For pool service professionals with high testing volume, a photometer with bulk reagent refills is usually the most economical choice.

Colorblind-Friendly Pool Testing

One of the most underrated benefits of digital pool chemistry test kits is that they solve the colorblind testing problem entirely. Traditional test strips and drop-based kits require accurate color matching, which is genuinely difficult for the 8 percent of men and 0.5 percent of women with red-green color vision deficiency. Digital testers display numerical readings, so color vision is irrelevant. For colorblind pool owners, any of the digital meters on this list will be a major upgrade over strips or drop tests.

Digital Pool Chemistry Test Kits FAQs

Final Verdict: Which Digital Pool Test Kit Should You Buy in 2026?

After testing all 8 digital pool chemistry test kits above for accuracy, ease of use, and real-world reliability, here is how I would match them to specific pool owners. If you want a set-and-forget continuous monitor and you like the idea of pool chemistry data on your phone, the LKBird Smart Pool Monitor is the best digital pool chemistry test kit of 2026. If you want a handheld digital pool tester with broad parameter coverage at a budget price, the Terronix 7-in-1 is the strongest value pick. If you want the simplest, cheapest entry point into pool chemistry testing, the Bliss Pool 7-in-1 strips with app scanning get you started for under 12 dollars.

For saltwater pool owners specifically, the LKBird continuous monitors or the AIPER HydroComm are the strongest picks because they cover salinity alongside the rest of the chemistry panel. For new pool owners who do not yet know which parameters matter most, the Droplytix 10-in-1 strip system or the AKSBTEC 11-in-1 combo kit covers the full residential chemistry panel from a single purchase. Whichever kit you choose, moving from manual color matching to digital pool chemistry testing will save you time, reduce frustration, and help you catch chemistry problems before they turn into expensive pool repairs.
