Hydrogen peroxide vapor, relative humidity saturation level, for relative humidity measurement.
The PEROXCAP measurement uses two Vaisala HUMICAP sensors. One has a catalytic layer, and the other does not. HUMICAP is a polymer film capacitive sensor that has a polymer thin film sandwiched between two electrodes on an alumina substrate. In the PEROXCAP measurement, the concentration of hydrogen peroxide vapor is indicated by the difference in the measurement values of the two sensors.
