HS5 - Hygrostat / Thermostat

The transmitters in the HS5 series are progressive transmitters for accurate measurement of relative humidity and temperature and can convert these to psychrometric parameters as required by the application concerned. Their measurement results can be read out via analog outputs or Ethernet. A relay switches when the switching threshold that has been set is reached. The instruments measure with interchangeable HygroClip2 probes, enabling an unprecedented class of accuracy.
The HS5 boasts a unique calibration and adjustment process and many other unbeatable features. At the same time ROTRONIC has also improved the sensor technology, taking humidity and temperature measurement to a whole new level of performance and reliability: the HS5 transmitters offer repeatability of < 0.02 %RH and with the HC2-S guaranteed system accuracy of < 0.8 %RH and 0.1 K.

The Applications

The HS5 series is ideal for wherever exact measurement of humidity and temperature is of critical importance: in the food and pharmaceutical industries, printing and paper industries, meteorology, the agricultural sector, archeology, HVAC applications, etc. There is hardly a sector today in which these parameters can be ignored. The measurement task in question ultimately defines which instrument best covers your needs.
