Comparing sensors for effective vaporized H2O2 measurement

What kind of sensor should you select for measuring humidity under vaporized hydrogen peroxide?

In this application note "Humidity measurements in vaporized hydrogen peroxide bio-decontamination applications" we describe the impact of VH2O2 on humidity measurement and how to select the right sensor. We compare  HUMICAP® sensors, Catalytic HUMICAP® sensors, and the PEROXCAP® sensor to show how features such as chemical purge, which is standard in the HPP270 series probes, ensures repeatable, accurate measurements.

The Vaisala PEROXCAP® HPP270 series probes feature both digital and analog outputs. The probe was developed for manufacturers, service providers, and end-users who use vaporized H2O2 in bio-decontamination processes. In addition to H2O2, the probe measures temperature and humidity, referring to relative saturation and relative humidity, dew point, and vapor pressure. The probes can be used for both monitoring and control. To learn more about how the HPP270 series probe can ensure effective bio-decontamination, see the articles below.
