Vaisala HUMICAP Humidity and Temperature Probe HMP3 is a general-purpose probe designed for processes with moderate humidity and temperature levels. The probe structure allows the sensor to be replaced in the field without tools, making it suitable for applications such as industrial HVAC systems, paint booths, cleanrooms, environmental chambers, and applications where periodic recalibration is not sufficient for maintenance.

HMP3 is part of the Indigo family and is compatible with Indigo500 and Indigo200 series transmitters. It can be used with Vaisala Insight PC software for data visualization, easy probe configuration, and field calibration.
