DULCOTEST CLE 3-mA
Free chlorine sensor for use in clear water.
Standard sensor for measuring free chlorine in clear water. For operation on measuring devices with 4-20 mA input.
We currently only offer an extract from our product portfolio, other variants are available on request.
Send Request- Measured variable: free chlorine, no significant cross-sensitivity to combined chlorine (chloramines)
- Membrane-covered sensor (encapsulated) reduces interference from variable flow or water constituents
