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.
