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 Defined measurable range within which the errors in a measured variable remain within defined limits. more in the glossary of up to 100,000 mg/l.

The PEROX H2.10 P sensor has no cross-sensitivity to chlorine and peracetic acid Peracetic acid is particularly used in the food and beverage industry, but also for disinfection in ... more in the glossary, and with its fast response time and separate temperature measurement, can be used to control fast processes in clear water, even with the intermittent absence of hydrogen peroxide Due 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 and also in moderately contaminated water.

Your benefits

  • Precise, real-time amperometric measurement for efficient process control (short response time)
