What kind of sensor should you select for measuring humidity under vaporized hydrogen peroxide?
In this application note "Humidity measurements in vaporized hydrogen peroxide bio-decontamination applications" we describe the impact of VH2O2 on humidity measurement and how to select the right sensor. We compare HUMICAP® sensors, Catalytic HUMICAP® sensors, and the PEROXCAP® sensor to show how features such as chemical purge, which is standard in the HPP270 series probes, ensures repeatable, accurate measurements.
The Vaisala PEROXCAP® HPP270 series probes feature both digital and analog outputs. The probe was developed for manufacturers, service providers, and end-users who use vaporized H2O2 in bio-decontamination processes. In addition to H2O2, the probe measures temperature and humidity, referring to relative saturation and relative humidity, dew point, and vapor pressure. The probes can be used for both monitoring and control. To learn more about how the HPP270 series probe can ensure effective bio-decontamination, see the articles below.
During customer site visits we witness industry trends in bio-decontamination and sterilization. Many of our customers and original equipment manufacturers (OEM) anticipate an increase in the use of vaporized hydrogen peroxide over ethylene oxide. To understand this trend, it is useful to compare vaporized hydrogen peroxide to ethylene oxide to define applications that are best served by each.
During our live webinars, we receive many questions on H2O2 bio-decontamination. In this blog we answer some of the most common questions, including:
A bio-decontamination service provider compares the equipment he normally uses with the Vaisala HPP272 probe combined with the Indigo201 transmitter. In this blog, he gives his evaluation and a link to the results of the comparison.
In this application note, we look at vaporized hydrogen peroxide in isolators, closed restricted access barrier systems (cRABS), and transfer hatches (TH). Although the focus is on isolator bio-decontamination, the same principles also apply to other safety and purity units.
Hydrogen peroxide generators are used for room bio-decontamination in intensive care units, operating and emergency rooms, ambulances, blood banks, food and beverage processing and storage areas, animal facilities and labs, procedure rooms and more... In this application note we outline the use of vaporized hydrogen peroxide in large chambers and rooms.
There are different ways to verify that a vaporized hydrogen peroxide bio-decontamination process is working effectively, each with its own pros and cons. In this blog we look at common methods and compare.
