Vaisala HPP270 Series Vaporized Hydrogen Peroxide, Humidity and Temperature Measurement

Product Details

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.

Key benefits

Measures reliably and accurately even in high humidity
Intelligent measurement technology including the chemical purge function helps to maintain accuracy between calibrations in challenging environments. The purging process involves rapid heating of the sensor to remove possible contamination. The PEROXCAP sensor used in the HPP270 series probes is warmed, which prevents condensation from forming on the sensor. This provides reliable measurement even in condensing conditions.

3 measurement parameters in 1 instrument
In addition to hydrogen peroxide, the compact HPP272 measures temperature and humidity, referring to both relative humidity and relative saturation. This gives exact hydrogen peroxide readings in ppm throughout the whole bio-decontamination cycle. Dew point and vapor pressure measurements are possible.

Successful audits
Repeatable measurement helps you pass audits and regulatory inspections successfully
