10 Best Ph Test Kits 2025 in the United States

The EASYTEST 7-Way Pool Test Strips offer a convenient solution for testing water chemistry in pools, hot tubs, and spas. With 150 strips included, they are quite affordable and suitable for frequent testing. These strips can evaluate seven critical parameters: Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine, making them comprehensive for standard water testing needs.

The process is straightforward—simply dip a strip in water, wait for 15 seconds, and compare it against the color chart on the bottle for quick results. The strips utilize high-quality fiber paper, which is designed not to bleed and ensures accurate readings if the instructions are followed properly. No calibration is required, which simplifies maintenance. However, for best results, it is essential to avoid touching the strips with wet fingers and to read the results under natural daylight.

The strips are durable if stored correctly in a cool, dry place but need to be used within 90 days of opening to ensure accuracy. One potential drawback is the limited shelf life once the container is opened, which might lead to wastage if not used frequently enough. Additionally, while easy to use, some users might find comparing colors on a chart less precise compared to digital meters. The EASYTEST 7-Way Pool Test Strips are a practical, cost-effective choice for regular water quality monitoring, especially for those who prefer a non-digital, low-maintenance option.

The Apera Instruments Premium-Series PH60S Food pH Pocket Tester Kit is designed mainly for food-related pH testing, including cheese, sushi rice, meat, and dairy products, but it also works well with general water solutions. It offers a wide pH range from -2.00 to 16.00 and has excellent accuracy at ±0.01 pH, which means it can detect very small differences in acidity or alkalinity. The Swiss spear sensor is durable and features a replaceable long-life reference system, helping to extend the device’s lifespan. Calibration is user-friendly with automatic temperature compensation and an easy auto-calibration process.

The large LCD screen with backlighting is clear and changes color to indicate different modes, making it easier to read results even in dim lighting. A helpful feature is the high/low alarm that alerts you instantly if a pH reading falls outside your desired range. This kit comes complete with everything needed to start testing right away, including calibration and storage solutions, batteries, and a carrying case for portability.

The device is made in China, which may concern some about build quality, although Apera generally has a good reputation. The probe sensor, while replaceable, may require care to maintain accuracy over time, and the kit’s compact size means the screen and buttons are small, which could be tricky for users with limited dexterity. This tester is well suited for anyone needing reliable, precise pH measurements in food or water, especially if convenience and clear results in a portable package are important.
