JUMO tecLine TC – Sensor for Total Chlorine (202631)



  • Three-electrode principle
  • Easy calibration
  • Integrated temperature compensation
  • Proven measuring system
  • Analog and digital version


  • Drinking water monitoring
  • Swimming pool monitoring




This membrane-covered amperometric sensor is used to measure the total chlorine concentration in water.

The sensor also measures "free chlorine" from anorganic chlorine products (chlorine gas, hypochlorite, etc.) and "combined chlorine" (e.g. chloramine).

This sensor can only be used in media with drinking or swimming pool water quality.

Typical areas of application include swimming pools and monitoring of drinking water.

The sensors are not suitable for detecting the absence of chlorine.

The integrated electronics of the sensors provide a temperature-compensated current signal of 4 to 20 mA. A downstream device (indicator, controller, recorder, PLC, etc.) is used for calibration.

The sensors can be connected directly to a suitable display and control device.

The display/control device JUMO dTRANS AS 02 (data sheet 202553) or the JUMO AQUIS 500 AS (data sheet 202568) are especially suitable for the combination with these sensors. They provide the voltage required for the supply of the sensors and allow for easy calibration of the measuring system.
