Bio-decontamination

What's new?

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 measurement is needed.

The new 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. Scroll down to learn more!

Vaisala Vaporized Hydrogen Peroxide Bio-decontamination Process Simulator

H2O2 Calculator

With this vaporized hydrogen peroxide calculator, you can simulate bio-decontamination processes in closed and open systems, or under free evaporation conditions. Simply choose your method and input parameters like: phase duration, temperature, injection rates, H₂O₂ liquid concentration, and other parameters. Model your process in the simulator and see the effects on the condensation point, relative humidity, relative saturation, and achievable vH₂O₂ ppm concentration.

How to use:
•   Choose your bio-decontamination method: Closed system, Open system, free evaporation
•   Enter process parameters
•   View results

Ecological bio-decontamination

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 several 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. The repeatable measurement in rooms, isolators, transfer hatches, vapor generators or other equipment makes passing regulatory audits easier giving reliable results even in high humidity near condensation.

Recorded online training

Watch this recorded webinar "Humidity measurement in H2O2 bio-decontamination – relative saturation as the key" to understand the relationship between the key parameters in bio-decontamination with vaporized hydrogen peroxide; specifically relative saturation and relative humidity.

Our industry experts demonstrate how using relative saturation as a key parameter will improve vH₂O₂ bio-decontamination efficacy and process control. All questions from this webinar were answered in this blog "An in-depth look at Vaisala’s hydrogen peroxide sensor technology."
