Reliable online measurement of total chlorine – with DULCOTEST sensors.
Total chlorine refers to the total amount of free chlorine (HOCl, OCl-) and combined chlorine (chloramines). Sensors for total chlorine are used in chloramination, chlorine elimination and waste water monitoring. The total chlorine measurement is also used in conjunction with the measurement of free chlorine to measure the amount of combined chlorine in swimming pool water.
Our product line of DULCOTEST sensors for total chlorine includes the versatile CTE1 range with different measuring ranges and signal outputs.
Features and Benefits
- Versatile use with a wide range of water qualities (pH, salinity, temperature, chemical and contamination load); in combination with many disinfection processes (chlorine gas, sodium hypochlorite, calcium hypochlorite, chloramines); can also be used at high pH values up to 9.5
- Precise, real-time amperometric measurement for efficient process control (short response time)
- Amperometric measuring eliminates interference caused by turbidity or colouration
- Integrated temperature compensation eliminates interference caused by influence of temperature
- Diaphragm-covered electrodes for reduced dependence on flow, substances in water and film-forming media
- Diaphragm-covered measuring electrodes embedded in an electrolyte ensure long service life. This maintains optimum measuring conditions regardless of process conditions.
Technical Details
Total chlorine
- CTE 1; pH: 5.5 … 9.5; Temperature 41 … 113 °F (5 … 45 °C)
Sensor for Total Chlorine CTE 1-mA
Sensor for total chlorine, including, for example, free chlorine, chloramines etc. even with high pH values in different kinds of water. For use on controllers with mA input
Your Benefits
- Measured variable: Total chlorine, chlorine compounds, in which chlorine acts as an oxidising agent, e.g. free chlorine (HOCl and OCl-), chloramines etc.
- Diaphragm-covered sensor (encapsulated) prevents faults caused by changing flow or ingredients in the water
- Hydrophilic diaphragm guarantees permeability for different water-soluble oxidising agents towards the measuring electrodes
- The special reaction system of the electrolyte allows components containing oxidising chlorine to be determined and used at a high pH of up to 9.5
