The Vaisala PEROXCAP® Hydrogen Peroxide, Humidity, and Temperature Probe 

HPP270 series probes are designed for demanding hydrogen peroxide bio-decontamination. The probes are ideal wherever repeatable, stable, and accurate measurement is essential and suitable for a variety of applications such as isolator, material transfer hatch, and 

room bio-decontamination.

The basic probe option HPP271 is for measuring only H2O2 vapor concentration. The advanced
HPP272 probe measures all relevant parameters during bio-decontamination processes, including hydrogen peroxide vapor, temperature and humidity as relative saturation and relative humidity, dew point and vapor pressure.

The probes can be used as standalone devices, or with Vaisala Indigo transmitters: Indigo200 transmitters and Indigo520 transmitters. For easy-to-use access to configuration, calibration and adjustment the probe can be connected to Vaisala Insight PC software.
