Relative Humidity and Temperature Probe HMP8
for pressurized processes
Vaisala HUMICAP® Humidity and Temperature Probe HMP8 is designed for pressurized applications in compressed air systems, refrigerant dryers, and other pressurized industrial applications where easy insertion and removal of the probe and adjustable installation depth into the pipeline are needed. The HMP8 is part of the Indigo product family and compatible with Indigo500, Indigo300 and Indigo200 series transmitters and free Insight PC Software.
New: two probe lengths
The HMP8 is available in two probe lengths:
standard 268 mm
longer 454 mm
The longer probe ensures accurate results even with thick wall insulation in compressed air systems.

Key benefits
Proven Vaisala HUMICAP performance
Vaisala is the original innovator of the thin-film capacitive humidity measurement technology, which has now become the industry standard in humidity measurement.
Chemical purge minimizes effects of contaminants
In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals.
Flexible connectivity
The probe is plug and play compatible with Vaisala Indigo series transmitters, can be used as a standalone digital Modbus RTU transmitter, or connected to Vaisala Insight™ PC Software.
