PRH-631 – Relative Humidity and Temperature Sensor - wall mount

Relative Humidity and Temperature Sensor - wall mount


The new RH-600 range of humidity and temperature sensors offer the latest technology high precision and accuracy RH & T element, and installed in our new revised robust 600 series housing. The housing has an added benefit of being easy to install with the new hinged lid, which can also be screwed closed to make the unit tamperproof. An optional multi-line backlit LCD display is available, along with a direct PTC/NTC sensing element (when this option is required, the type of element must be specified at the time of ordering).
