ProMinent Dulcotest - Sensors for Hydrogen Peroxide

Reliable online measurement of hydrogen peroxide with DULCOTEST sensors.

You have the choice of three types of sensor for applications with different requirements with our DULCOTEST sensors for hydrogen peroxide (H2O2): PER1, PEROX H2.10 P and PEROX H 3E.

The PER1-mA sensor is resistant to contaminated water and can be used in water with a temperature of up to 50 °C. It is a compact sensor with a built-in transducer and temperature correction, and has a measuring range of up to 100,000 mg/l.

The PEROX H2.10 P sensor type displays no cross-sensitivity to chlorine and, with its fast response time and separate temperature measurement, can be used to control fast processes in clear water, even with the temporary absence of hydrogen peroxideDue to its complete biodegradability, hydrogen peroxide is a disinfectant and oxidising agent ...more in the glossary.

The PEROX H 3E sensor with a built-in transducer and 3-electrode system shares the benefits of the PEROX H2.10 P sensor and can also be used for reliable measurement above 0.2 ppm H2O2 as well as being suited to moderately contaminated water.

• Precise, real-time amperometric measurement for efficient process control (short response time)
  
• Amperometric measuring eliminates interference caused by turbidity or colouration
  
• Stable zero point means no drift
  
• Temperature compensation eliminates interference caused by the influence of temperature
  
• Diaphragm-covered electrodes for reduced dependence on flow and cross-sensitivities
  
• Short run-in period for quick commissioning

• pH-range of 1-11 (variable), suitable for use at a constant pH value of up to pH 12 (types PER 1, PEROX H2.10 P)
  
• PER1 and PEROX H-3E sensor types can also be used with contaminated process media
  
• Maximum operating temperature of up to 50 °C (type PER 1)
