Overview of sensors for hydrogen peroxide​​​
Hydrogen peroxide sensor PER 1-mA
Sensor for the measurement of hydrogen peroxide even in chemically contaminated and polluted water. Available with measuring ranges for medium to very high concentrations
​
Your Benefits
â– Hydrogen peroxide as the measured variable, with measuring ranges from 20 ppm to 100,000 ppm (10%. With > 2%, as special versions)
available
â– Diaphragm-covered sensor minimises faults caused by changing flow or substances in the water
â– Resistance to films of dirt thanks to use of a pore-free diaphragm
â– Can be used in wide pH range of 1...11
â– Operating temperature up to 50 °C
​
Important note: Measuring ranges up to 100,000 ppm on request
​
Hydrogen peroxide sensor PEROX H2.10 P-mA
Sensor for measuring hydrogen peroxide without cross-sensitivity to chlorine. It can also be used for fast control processes even with the temporary absence of hydrogen peroxide in clear water in a wide pH range of 2.5...10.
​
Your Benefits
â– Measured variable hydrogen peroxide without cross-sensitivity to chlorine
â– Diaphragm-covered sensor minimises faults caused by changing flow
â– Fast processes can be controlled through the sensor’s rapid response time in conjunction with fast external temperature measurement for
temperature correction
â– Can be used in wide pH range of 2.5...10
â– Reliable measurement even after periods of absence of hydrogen peroxide thanks to pulsed, self-regenerating measuring electrode
​
Hydrogen peroxide sensor PEROX H 3E-mA
Sensor for the measurement of hydrogen peroxide without cross-sensitivity to free chlorine peracetic acid. Suitable for use with fast control processes, even in moderately contaminated water, and for reliable measurement from 0.2 ppm H2O2
​
Your Benefits
â– Measured variable hydrogen peroxide without cross-sensitivity to free chlorine and peracetic acid
â– Sensitive measuring range from 0.2 mg/l
â– Fast processes can be controlled through the sensor’s rapid response time in conjunction with fast external temperature measurement for
temperature correction
â– Reliable measurement even after periods of absence of hydrogen peroxide thanks to pulsed, self-regenerating measuring electrode
â– Low measuring range provided by a system containing 3 electrodes
â– Membrane-covered sensor minimises faults caused by changing flow
â– An integrated transmitter and the signal cable’s plug-in connector make for an easy installation
