The WQ422 sensor is a compact and robust instrument suitable for measuring PH in underground and surface water.
The signal produced in mA is directly proportional to the PH of the liquid being measured.
The WQ422 sensor produced in compact dimensions, with a diameter of 35mm, allows its insertion in small-sized wells.
Every sensor is provided with a calibration certificate that attests the results of the test performed and all electromechanical features.
