Because of their reliable accuracy and precision, our HYGRASGARD® humidity sensors and humidity meters are well-established in many sectors of building automation up to clean room technology and OP rooms.

With measurement ranges from 0 % to 100 % relative humidity at operating temperatures from -35 °C to +80 °C, each S+S humidity sensor covers a broad spectrum of standard as well as technical applications, with humidity sensor for measurement tolerances and control tolerances of max. ± 2 % or ± 3 % r.H. where required. As with all S+S humidity sensors, operability and design benefit from the uniform look & feel of the patented enclosure series Frija and Thor.  

S+S is innovating! Our versatile HYGRASGARD® duct humidity sensors and on-wall humidity sensors are now also available in versions with pluggable sensor. Of course in long and compact form, with or without display, and in two accuracy classes as before.
That way defective sensors can be replaced without special knowledge during uninterrupted production. Ideal for processes generating great amounts of dust, dirt carriage, or splash water exposure.

Humidity is a must at many processing applications, at others it's a threat. Our HYGRASGARD® humidity sensors have proved in thousands of sophisticated installations. From controlling moisture on ceiling pipes to prevent damages caused by dripping up to measurement of absolute humidity at compressors. Also available with output indicating mixture ratio where required. And in any case readjustable.
