The Vaisala HUMICAP® HMP3 Humidity and Temperature Probe is a general-purpose industrial probe for humidity and temperature measurement in processes with moderate humidity and temperature levels.
It is designed for use in applications such as industrial HVAC systems, paint booths, cleanrooms, environmental chambers, and similar controlled process environments.
As part of the Vaisala Indigo Family, the HMP3 can be used as a standalone device through Modbus RTU over RS-485 or paired with compatible Indigo series transmitters for additional display, configuration, connectivity, supply voltage, and wiring options.
Process Controls Corporation supplies the HMP3 for industrial customers who need a supported humidity and temperature probe for general-purpose process measurement applications.
