Humidity & Temperature Probe (HMP1)

For Wall Mount

Vaisala HUMICAP® Humidity and Temperature Probe HMP1 is designed for measuring ambient measurement in indoor spaces. HMP1 can be directly connected to Indigo200 series transmitters to form a single wall-mounted unit. Its probe head and body are integrated to a single unit, and it uses the miniature 5 mm (0.2 in) diameter HUMICAP® sensor and head for great stability and fast response time. 

HMP1 is part of the Indigo product family and compatible with Indigo200 and Indigo500 Series Transmitters. HMP1 can also be used with the Vaisala Insight PC Software for data visualization, easy probe configuration and self-calibration.​  

Humidity & Temperature Probe (HMP3)

For ppm-level measurements in agriculture, refrigeration, demanding HVAC & for plant growth manufacturers

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.
