4-in-1 Digital pH Meter Tester: This pH meter is designed with a 4-in-1 function that can simultaneously measure pH, TDS, EC, and temperature with high accuracy and speed. Omnidirectional measurement ensures healthy water quality. The electronic pH meter boasts reliable quality, durable ABS material, an IP67 waterproof rating, an ergonomic pocket size, and the best price, making it your first choice for water quality testing.

±0.01 pH Measurement Accuracy: With a high-sensitivity glass probe, the full measurement range of this pool water tester is 0-14 pH, with a resolution of 0.01 pH.

The pool pH tester uses a 3-point calibration method, calibrating the electrode to solutions of pH 4.00, pH 6.86, and pH 9.18 to ensure accurate measurements. Easy to Calibrate: Simply immerse the electrode in the target solution, then press and hold the MODEL/CAL button for 5 seconds after taking readings to stabilize (usually 5 to 10 seconds). Calibration will then be performed automatically. A large backlit LCD screen and dual temperature and pressure displays help you obtain accurate and quick readings. If there is no operation within 5 minutes, the pH tester will automatically shut off. Automatic Temperature Compensation (ATC): No need to worry about the temperature of the liquid being tested. The pH meter can accurately determine the pH value of the sample within a temperature range of 0°C-60°C (32°F-140°F), thus resolving the problem of inaccuracy caused by variations in liquid temperature. Wide Application: We have covered all the electronic pH meter occasions you need! With its pocket-sized format, the pH tester is ideal for everyday use at home, in education, and for testing. The pH tester is suitable for testing the pH of drinking water, swimming pools, aquariums, spas, hydroponic systems, food, wine, beer, etc.
