Joint MCA-CL residual chlorine analyzer for tap water, industrial wastewater, wastewater treatment, seawater treatment, swimming pools, and end of pipe residual chlorine monitoring_

The residual chlorine measurement is based on the working principle of the three electrode film current method. The residual chlorine factor enters the sensor through a permeable membrane and undergoes redox reactions on the surface of the gold electrode, generating a weak current. The signal value obtained through processing is proportional to the concentration of residual chlorine or total chlorine. After calculation, the concentration of residual chlorine or total chlorine can be obtained. The selective permeation of the membrane and electrolyte determines the factor composition of selective passage, thereby reducing the influence of pH on the sensor.
