HPP270

PEROXCAP® vaporized hydrogen peroxide probe for bio-decontamination

A probe series with PEROXCAP® technology for measuring vaporized hydrogen peroxide (VHP) in demanding bio-decontamination of isolators, transfer hatches and rooms. The HPP271 option measures H2O2 concentration; the HPP272 adds humidity, temperature and relative saturation in a single stainless-steel probe. Heated sensor and purge function for repeatable measurement even in condensing conditions.

Features

Key features

PEROXCAP® technology with two HUMICAP® sensors, one with and one without a catalytic layer, to separate H2O2 from humidity
Relative saturation measurement: shows when bio-decontaminated air starts to condense
Heated sensor that prevents condensation from forming on the sensing element
Purge function with rapid heating that removes impurities and maintains accuracy between calibrations
HPP272: up to three measurements (H2O2, humidity and temperature) in a single compact probe
Traceable factory calibration certificate (2 points H2O2, 3 humidity, 1 temperature)
