Up to Three Measurements in One Compact Unit

The advanced HPP272 probe option provides all the parameters you need to measure during bio-decontamination processes: hydrogen peroxide vapor, temperature, and humidity as relative saturation and relative humidity.

Repeatable Measurement for Highly Condensing Environments 

Intelligent measurement technology including the chemical purge function helps to maintain accuracy between calibrations in challenging H2O2
environments. The purging process envolves rapid heating of the sensor to remove possible contamination. The PEROXCAP sensor used in the HPP270 series probes is warmed, which prevents condensation from forming on the sensor. This provides reliable measurement even in condensing conditions.

Relative Saturation for Comprehensive Humidity Monitoring

Similar to water, H2O2 vapor affects the humidity level of the decontaminated air. The advanced HPP272 probe option enables the measurement of relative saturation, which indicates the total humidity level caused by water vapor and H2O2 vapor together. This tells you reliably when the bio-decontaminated air starts to condense.

Indigo and Insight Compatible

Vaisala Indigo transmitters provide additional features such as analog and digital outputs, relays, and a smartphone configuration interface. For easy-to-use access to configuration, calibration, and adjustment, the probe can be connected to Vaisala Insight PC software.
