Hydrogen peroxide (H2O2) is used to sterilize clean rooms, incubators, and other equipment. In the process, humidity is crucial for effective sterilization.
H2O2 hinders the measurement of water vapor by occupying the pores on the sensor’s surface. It can also attack sensitive materials such as the polymer used in humidity sensors. Conventional humidity sensors have difficulty measuring accurately at high H2O2 concentrations and often fail.
Not so with the latest PST humidity probe range “Rotronic HC2A-X-HH”. Due to the specially developed Hygromer-HH-1-SK sensor with additional protective lattice, it is more resistant to H2O2 and the service life is considerably extended compared to standard sensors for these applications. The Hygromer-HH-1-SK sensor has already been proven under sterilization conditions for over ten years. Some of the largest suppliers of H2O2 decontamination equipment have partnered with PST and rely on our measurement technology and expertise to ensure their solutions are effective and safe for their clients.
