Rotronic – Humidity & Temperature Sensors

Rotronic humidity and temperature measurement sensors enable high performance, reduced energy consumption and increased safety. If temperature can affect any process or performance balancing the humidity should be an option that is taken into consideration as temperature is critical to the correct measurement and interpretation of humidity.

Rotronic product offering includes data loggers, indicators, transmitters, probes and generators. These humidity and temperature instruments are able to calibrate and correctly measure dew point, relative humidity, water activity and other humidity parameters.

These instruments are suitable for use in numerous industries including pharmaceutical, food/beverage, HVAC, mining and hazardous areas.
