4 - 20MA Output Free Chlorine Sensor CL4.2 With Flow Cell For Drinking Water

4-20MA Output Free Chlorine Sensor CL4.2 With Flow Cell For Drinking Water

Amperometric Membrane Method (Amperometric Membrane Method) residual chlorine sensor CL4.2 is a sensor technology commonly used to measure the concentration of residual chlorine in water. It is based on the principle of electrochemistry, by measuring the current to determine the content of residual chlorine in the water sample.

Specifications

Chlorine sensor with membrane-covered, amperometric 2-electrode system. For the measurement of free inorganic chlorine at constant pH.
