TRC residual chlorine analyzer

● Drinking water, swimming pool ● Sewage treatment ● Pharmaceutical, beverage ● Electricity, hospital, etc.

Residual chlorine electrode uses electrochemical method (Amperometric method). The chemical reaction occurring on the electrode will generate a current, which is proportional to the concentration of the analyte. The common electrode method residual chlorine / chlorine dioxide / ozone sensor is a two electrode system.

TRC uses an advanced amp 3 electrode measurement system to make the measurement more stable and the working life longer.

● Imported 3-electrode system, high measurement reliability;

● The electrode, flow cell and flow meter are installed on the same panel, and the flow rate can be controlled;

● The electrolyte and membrane cap are easy to replace, and the replacement cycle is long;

● Low pH dependence

● Can withstand a small amount of surfactant
