Simply press the {MODE/CAL} key to switch the value of pH, EC (uS/cm), TDS (ppm), and salinity (ppm/%).3 Salinity Test Application Ranges: Salinity Test (0-9999ppm), Seawater Test (10-200ppt), (1ppt=1000ppm, when the ppm number exceeds 9999ppm, the pH meter will automatically switch to the ppt unit display). Food test (0.01-25%). When testing food, select the appropriate measurement mode and unit to ensure accurate and reliable measurement results. The units of TDS and salinity are the same, but when measuring salinity, the pH meter needs to be converted to salinity mode.High Precision & Easy to Use: The digital pH tester is equipped with high-quality platinum-plated electrodes, and high-precision algorithm chips
