Vaisala PEROXCAP® HPP272

for Vaporized Hydrogen Peroxide, Humidity and Temperature Measurement in Bio-Decontamination Processes

The Vaisala PEROXCAP® HPP272 is a new, intelligent 3-in-1 measurement probe with both digital and analog outputs. It has been developed for manufacturers, service providers and end-users who use vaporized H2O2 for bio-decontamination processes. In addition to H2O2, the compact HPP272 measures temperature and humidity, referring to both relative humidity and relative saturation. This 3-in-1 probe is ideal for applications such as isolators, transfer hatches, and room bio-decontamination. The probe can measure reliably and accurately even in high humidity.


  • Superior long-term stability and repeatability
  • Traceable calibration certificate
  • Corrosion-resistant stainless steel housing (IP65)
  • Compatible with Indigo Output Transmitters when preferred
