Safe Water Treatment Thanks to Precise Chlorine Measurement with JUMO Sensors
Effective and reliable water treatment is virtually impossible without precise monitoring of the disinfection process. JUMO’s sensors and electrodes enable continuous measurement of free chlorine – one of the most important disinfectants in water technology.
Why Measure Free Chlorine?
In water treatment – whether for drinking water, swimming pools, or industrial processes – free chlorine ensures the safe elimination of germs and bacteria. The correct dosage is crucial:
Too little chlorine compromises water quality, while too much can be harmful to both humans and infrastructure.
JUMO’s sensors for free chlorine measurement operate according to the amperometric principle and offer the following advantages:
- Selective Membrane: Only free chlorine passes through the special membrane into the measuring cell.
- Reliable Measurement: The chlorine is electrochemically detected inside the cell – the resulting signal is directly proportional to the concentration in the water.
- Real-Time Monitoring: Ideal for automated control and regulation in water treatment systems.
Typical Applications
- Drinking water treatment
- Swimming pool and spa facilities
- Cooling and process water monitoring
- Food and beverage industry
These amperometric sensors with membrane are used to determine the concentration of free chlorine. They are able to measure various inorganic chlorine compounds, including chlorine gas (Cl₂), electrolytically generated chlorine, sodium hypochlorite (NaOCl), calcium hypochlorite (Ca(OCl)₂) and chlorinated lime (Ca(OCl)Cl). Testing for the complete absence of free chlorine is not possible with these sensors. Depending on the version, the sensors either supply a temperature-compensated current signal (4-20 mA) in an analogue version or a Modbus RTU signal via a digital interface. Calibration takes place in a downstream device such as an indicator, controller, recorder or programmable logic controller (PLC). The sensors can be connected directly to various transmitters or controllers. These supply the system with the required voltage and enable uncomplicated calibration. Areas of application: The sensors are used to measure free chlorine in drinking water, bathing water, industrial water, process water and cooling water.
