Specifications

Measurement Method
Self-cleaning three electrodes system that uses a platinum anode, a gold cathode electrode and a Ag/Agcl electrode to measure free residual chlorine. No need for chemical reagents, the rotor inside rotates continuously to clean the electrodes. An electrochemical reaction occurs within these electrodes, based on the free chlorine concentration, generating a proportional current.
