Description

Measured variable: total chlorine, chlorine compounds in which chlorine acts as an oxidizing substance, for example, free chlorine (HOCl and OCl), chloramines, etc..
Membrane-covered sensor (encapsulated) prevents interference from variable flow or water constituents
Hydrophilic membrane ensures permeability for different water-soluble oxidants towards the measuring electrode
Special reaction system of the electrolyte enables the determination of constituents containing oxidizing chlorine, as well as the application at high pH of up to 9.5
