JUMO tecLine Cl2, Sensor for Free Chlorine (202630)
- Two-electrode principle/three-electrode principle
- Easy calibration
- Integrated temperature compensation
- Proven measuring system
- Analog and digital version
- Drinking water disinfection
- Swimming pool disinfection
These membrane-covered amperometric sensors are used to measure the concentration of free chlorine (e.g. drinking water, swimming pool water, industrial water, process water, and cooling water).
The sensor for free chlorine can be used to measure the following anorganic chlorination agents: chlorine gas (Cl2), electrolytically generated chlorine, sodium hypochlorite (NaOCl, chlorine bleaching solution), calcium hypochlorite (Ca(OCl)2), or chlorinated lime (Ca(OCl)Cl).
The sensors are not suitable for detecting the absence of free 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.
