SMR03 Free Chlorine Analyzer for Water Quality

The free chlorine meter housing in a robust IP68 proof enclosure, 1000 N tensile strength cable, up to 1.2 km digital data transmission, the Chlorine meter is ideally used in water/wastewater industry.

The amperometric electrode measurement cell consists of two combination probes that uses a platinum cathode and a copper anode electrode to amperometrically measure free residual chlorine, There is no need for chemical reagents, and the glass balls inside rotates continuously to remove the hydrogen gas from the electrodes. An electrochemical reaction occurs within these electrodes, based on the available chlorine concentration, generating a propotional current. The whole unit includes flow indicator, free chlorine electrode and mounting plate. Optional pH and temperature sensors for compensation are available.
