PRH-1000 – Relative Humidity and Temperature Sensor

Space Relative Humidity & Temperature Sensor


The PRH-1000 uses the highest precision HR & T, the new PRH-1000 offers new options such as the adjustment of the nominal value, the momentary switch and selection of fan speed, along with a multi-line backlit LCD display. A 0-10Vdc input is available, allowing indication of occupancy in the display.

Outputs from 0 to 10 Vdc or 4 to 20 mA of temperature and relative humidity are available as standard with the optional 0-5Vdc. A custom output range for temperature may be required, between 0 ° C and 50 ° C.


-High stability and reliability
-Self-detecting output (-UN types)
-Designed to be aesthetically pleasing
-Blends into the fabric of any building
-Developed using customer feedback and involvement
-Fully configurable LCD display option.
