Vaisala Humidity and Temperature Probe HMP3
Please contact us if you are interested in this product.
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 Indigo 500 and Indigo 200 series transmitters. It can be used with Vaisala Insight PC software for data visualization, easy probe configuration, and field calibration.
- RH accuracy up to 0.8 %RH and temperature accuracy up to 0.1 °C (0.18 °F)
- Temperature measurement range -40 ... +120 °C (-40 ... +248 °F)
- Compatible with Indigo series transmitters
- PPS plastic grid filter with stainless steel mesh delivered as standard
- Modbus RTU over RS-485 for flexible connectivity
- Includes traceable calibration certificate
It uses Vaisala’s thin-film capacitive humidity measurement technology, which is now the industry standard in humidity measurement. Vaisala’s HUMICAP® technology provides the best stability, a fast response time, and low hysteresis in a wide range of applications.
HMP3 is part of the Vaisala Indigo family, so it can be used with Vaisala Indigo series transmitters. The transmitters offer various additional benefits such as a display for data visualization, easy access to probe configuration, and more extensive options for connectivity, supply voltage, and wiring.
Whether using the HMP3 on its own or with an Indigo transmitter, it can be connected to the free Vaisala Insight software for easy field calibration, probe configuration, and device analytics.
