Description
Electrochemical sensor for measurement of chlorine concentrations from inorganic chlorine products in water.
The chlorine measuring probe is an electrochemical sensor for measuring the concentration of chlorine in water. The measuring cell captures free chlorine from inorganic chlorine products (hypochlorite, chlorine gas, etc.). The measuring method has a reduced pH dependency, so that pH fluctuations only have a limited impact on the measurement signal. pH value increases only lead to an approximately 10 % reduction of the measuring signal per pH unit. The Sensor has a plug and is not delivered with a fixed cable.
