DULCOTEST CTE

Summary

Product identification

DULCOTEST® Sensors for Total Chlorine, CTE 1 range.

General description

These sensors provide reliable online measurement of total chlorine, which includes free chlorine (HOCl, OCl⁻) and combined chlorine (chloramines). They are suitable for various water qualities and disinfection processes, including use at high pH values up to 9.5. The amperometric measurement offers real-time, precise readings with a short response time.

Fields of application

• Potable water
• Swimming pool water
• Industrial water
• Process water
• Waste water

Applications include chloramination, chlorine elimination, waste water monitoring, and in swimming pools, detecting combined chlorine when used with the CLE 3.1 sensor.
