Ecological bio-decontamination with vaporized hydrogen peroxide
Vaporized hydrogen peroxide is an ecological bio-decontamination agent that decomposes into water and oxygen, leaving no residue. This has led to its widespread use in bio-decontamination processes.
As a leading developer of measurement instruments for demanding environments, we set out to create the best possible technology for measuring those processes.
Repeatable measurements in rooms, isolators, transfer hatches, and other equipment ensures effective log kills and improves cycle development and process control.
Vaisala HPP270 Series Probes
The unique 3-in-1 probe PEROXCAP® HPP272 for measuring H2O2, humidity and temperature has been developed further and the accuracy is now in a wider temperature range. Furthermore, dew point and vapor pressure measurements are available.
There is also a new type of probe available; the HPP271 was developed for applications where only hydrogen peroxide (ppm) and temperature dew point measurements are needed.
The probes can be calibrated and adjusted on-site with humidity by using Vaisala Insight PC Software and a humidity calibrator such as Vaisala HMK15 salt calibrator.

Customer Testimonials
“With the Vaisala unit I’m getting humidity and temperature, along with H2O2 concentration. This gives a more complete picture of what’s occurring and that’s crucial in validation.”
Rick Nieskes, Ardien Consulting Services
“Today, Vaisala is the best technology on the market to measure the concentration of H2O2 reliably, accurately, and repeatably over time...”
Philippe Muylaert, STERIS SAS
