The WQ450 meter was designed to measure conductivity in groundwater and surface water .
Redox or ORP is the oxidation of water , and is used as an alternative way to measure the quantity of chlorine ( a strong oxidant) contained in the water.
The WQ450 redox meter is composed of a platinum wire and from a reference electrode . The signal produced in mA is directly proportional to the oxidation level.
Each sensor is supplied with a test certificate which certifies the results of the test performed and its electromechanical characteristics.
