The probes are suitable for a variety of applications such as isolator, material transfer hatch, and room bio- decontamination. -
Page 10: Basic Features And Options
• Analog output: 2 x 4 ... 20 mA (default). • Easy plug-in, plug-out. • Can be used as a stand-alone probe or with Vaisala Indigo 200 series transmitters. • Can be connected to Vaisala Insight software for configuration, diagnostics, and temporary online monitoring. -
Page 11: Esd Protection
2.4 ESD Protection Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits. Vaisala products are adequately protected against ESD for their intended use. However, it is possible to damage the product by delivering an electrostatic discharge when touching, removing or inserting any objects inside the equipment housing. -
Page 12: Understanding Relative Humidity And Relative Saturation

Page 16: H 2 O 2 Measurement
PEROXCAP sensor within a day, and the sensor will not recover. PEROXCAPâ sensor technology works using measurements from two Vaisala HUMICAPâ sensors. HUMICAP sensors guarantee quality and reliability, with their reputation for repeatability, accuracy, excellent long-term stability, and negligible hysteresis – even in the most demanding high-concentration H applications in atmospheric pressure. -

Thin film polymer between two electrodes. Alumina substrate. In addition to measuring vaporized H concentration, HPP272 provides measurement for relative saturation, relative humidity, and temperature. Relative humidity (RH) is a parameter that indicates the humidity value derived from water vapor only, whereas relative saturation (RS) indicates the humidity percentage derived from water vapor and H vapor together. -

Page 20: Condensation Monitoring
HPP272 User Guide M211972EN-B For condensation monitoring, choosing the right measurement location is very important. If the bio-decontaminated space has surfaces with a lower temperature than where RS is measured, condensation may start to form on those surfaces even before RS reaches 100 %RS in the exact measurement location. -
