Digital Water Quality Meter, 5in1: PH Salinity Temperature TDS EC Waterproof Water Quality Meter with Backlit
This water quality meter can measure pH, TDS (ppm), EC (conductivity), salinity (ppt) and temperature with high accuracy at the same time
High Precision: ph tester High precision algorithm chip and high sensitivity probe allow you to quickly get accurate results. The LCD screen design with green backlight allows you to easily read the measurement results in any conditions. Simply press the HOLD/TEMP key to lock the measured value and remove it for easy viewing
Automatic Calibration:
Automatic Temperature Compensation: The pH meter no longer needs to pay attention to the temperature of the test liquid, the meter can accurately determine the pH value of the sample within the temperature range of 0°C -60°C (32°F-140°F).
