Measurement probe for ecological bio-decontamination processes

Instrumentation company Vaisala has introduced the upgraded HPP272 and a new HPP271 measurement probe for the environmentally friendly hydrogen peroxide bio-decontamination processes. Both probe models continue to use Vaisala’s proprietary PEROXCAP sensor for measuring hydrogen peroxide bringing all the benefits of its world leading accuracy, repeatability, and stability into play.

The new Vaisala PEROXCAP Hydrogen Peroxide HPP271 measurement probe brings stable, repeatable and accurate H2O2 vapor measurements to those customers, who require only ppm (parts per million) measurements for example in vapour generators.

Also the flagship 3-in-1 PEROXCAP Hydrogen Peroxide, Humidity, and Temperature Probe HPP272 has been boosted by specifying the ppm measurement accuracy in a wide temperature range, varying from +5°C to +50°C. The upgraded Vaisala HPP272 continues to measure vaporized H2O2, temperature and humidity, referring to both relative saturation and relative humidity. In the upgraded probe, also the measurement accuracy of relative saturation has been improved. Additionally it features dew point and vapor pressure measurements.

Both of the newly launched smart probes incorporate a timesaving on-site calibration capability, which is enabled by Vaisala’s Insight PC Software. On-site calibration can be done either by using water vapor or with H2O2 vapour. The software allows convenient setup and diagnostics of the HPP probes and all other Indigo-compatible smart probes. The latest Insight PC Software allows now also short-term data logging for 48 hours.

The new probes are optimized to provide accurate and repeatable measurements even in high humidities. Both of the new probes have compact and corrosion resistant housing with IP65-rating. The probes incorporate also digital and analog outputs and annual calibration interval with traceable H2O2 factory calibration.

The Vaisala HPP272 has been widely adopted by the pharmaceutical industry, isolator and material transfer hatch manufacturers and for room bio-contamination purposes. It offers reliable and accurate continuous in situ measurements and supports successful regulatory audits.

Please join the webinar on November 28 at 5-6pm (EET) to learn more about measuring humidity in H2O2 bio-decontamination applications and the role of relative saturation measurement.
