Sensor for total chlorine
This membrane-covered, amperometric sensor measures the total chlorine concentration in water and acquires “free chlorine” from inorganic chlorination products (chlorine gas, hypochlorite, etc.) and “combined chlorine” (e.g. chloramine). It can only be used in water of drinking or swimming pool water quality.
