Vaisala PEROXCAP® Hydrogen Peroxide, Humidity and Temperature Probe HPP270 series is designed for demanding hydrogen peroxide bio-decontamination processes. The probes are suitable for a variety of applications such as isolator, material transfer hatch, and room bio-decontamination.
Hydrogen Peroxide, Humidity and Temperature Probe HPP272 provides measurement for vaporized H2O2 concentration, relative saturation, relative humidity, and temperature.
The H2O2 measurement is based on comparing the readings of two composite humidity sensors to determine the vapor concentration of H2O2. The probes are easy to install with a plug-in/plug-out M12/5 connection. The digital and analog output options include an RS-485 interface for Modbus communication and two current output channels (4 … 20 mA).

The probe is not intended for safety level measurement. |

The probe is not intended to be used in vacuum applications. |
| CAUTION When there is H2O2 in the probe's environment, the probe must always be powered on. When powered on, the PEROXCAP sensor is heated, which permits using the probe in condensing H2O2 conditions, maintains measurement performance, and lengthens the probe's lifetime. When the probe is powered off, exposure to H2O2 condensation can cause the PEROXCAP sensor to fail within a day, and the sensor will not recover. |
