3-in-1 Multifunctional Water Test Meter: pH, test strip function, and temperature are perfectly combined in one meter. The pH tester is convenient for your water pH testing needs, saving you time and money for water quality safety. High Accuracy & Fast Measurement: The algorithm chip and high-precision electrode of our digital water pH tester ensure accurate and fast response. With automatic temperature compensation, the pH meter can accurately determine the pH value of the sample within the temperature range of 0°C-80°C, to solve the inaccurate problem caused by the liquid temperature. Innovative Litmus Test Strip Function: Designed with Litmus test strip function, the color of the LCD screen will change with the change of pH value, just like the Litmus test paper. You can get the pH value faster and more accurately. In addition, the high-definition backlit LCD screen, dual data display, all details are intended for high accuracy and long-term use. Effortlessly Sustained Accuracy:
