Humidity Probe for Hydrogen Peroxide Environments H2O2 – Rotronic HC2A-S(M)-HH
The Probe for Hydrogen Peroxide Environments(H2O2).
Hydrogen Peroxide Sterilization
Hydrogen peroxide (H2O2) is used to sterilize cleanrooms, incubators and other equipment. In this process the air is saturated by gassing or spraying, resulting in the formation of a microfilm on all surfaces. The hydrogen peroxide kills off all microorganisms. The H2O2 is then either recovered mechanically or allowed to decompose naturally over a period of 48 hours to harmless H2O or O2. The humidity level during the application is crucial for the effectiveness of the process.
Standard humidity sensors have difficulty measuring accurately in high concentration H2O2 environments. The Hydrogen Peroxide inhibits the measurement of water vapour by occupying the pores on the surface of the sensor. This is why ROTRONIC has developed a special sensor, the HYGROMER® HH1-SK. The life of the sensor is greatly extended compared with that of the standard sensor for these applications. Please see the sensor data sheet for exact technical data on the sensor.
