10 Best Pool Testers 2025 in the United States

The EASYTEST 7-Way Pool Test Strips are designed to help you maintain your pool, hot tub, or spa's water quality easily and affordably. With 150 strips in one pack, you can test your water multiple times a week, ensuring it stays clean and safe. These strips test for seven essential parameters: Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine, giving you comprehensive insights into your water's chemistry in one go.

The testing process is straightforward: dip the strip in water for just one second, hold it horizontally for 15 seconds, and then compare it to the color chart on the bottle for results. The high-quality fiber paper and no-bleeding pads used in these strips contribute to their accuracy, making sure you get reliable readings. However, it's important to handle the strips with dry fingers and read them in natural daylight for the best accuracy. Once opened, the strips should be used within 90 days to ensure reliable results.

One potential drawback is that the strips’ accuracy may diminish if not stored properly or used within the recommended timeframe. Additionally, while the initial purchase is affordable, the need to use strips frequently means you may need to buy more relatively soon. These test strips are ideal for anyone looking for a cost-effective and easy way to monitor their pool or spa water quality without needing specialized equipment.

The JNW 7-in-1 Pool Test Strips are a convenient and affordable choice for anyone looking to regularly check their pool, spa, or hot tub water quality. These test strips are easy to use—you simply dip them into your water and compare the color changes against a chart. They measure seven important water parameters including free chlorine, bromine, pH, alkalinity, and hardness, covering the basics needed to maintain safe and balanced water.

Users report the strips provide quick and fairly accurate results, which is essential for keeping your water clean and safe. However, like many strip testers, the accuracy can sometimes vary depending on how carefully you follow the instructions and interpret the color chart. The pH range tested (7.2 - 7.8) fits well within the typical ideal range for pools.

One of the big perks is the large pack size—150 strips—making it economical over time, though the strips need to be used within about 90 days once opened to stay reliable. Proper storage away from moisture and sunlight is important to maintain their effectiveness. This product also includes a free eBook with useful tips, providing a nice bonus for beginners. While these strips are not as precise as digital testers or liquid kits, they offer a good balance of ease, speed, and cost-effectiveness. They are best suited for pool owners who want a simple, no-fuss way to monitor their water chemistry regularly without spending much, though those needing highly detailed or professional-level testing might consider other options.
