DULCOTEST CTE 1-mA
Total chlorine sensor for use in different types of water
Sensor for total chlorine, including e.g. free chlorine, chloramines, etc. even at high pH in various types of water. For operation on measuring and control devices with mA input.
We currently only offer an extract from our product portfolio, other variants are available on request.
Send Request- 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
