Humidity sensor
Our HYGRASGARD® humidity sensors for indoor and outdoor use measure the relative humidity and temperature of the ambient air. The sensor device calculates various values from these measured variables: relative humidity [% r.H.], absolute humidity [g/m³], mixing ratio [g/kg], dew point temperature [°C], enthalpy [kJ/kg] and room temperature [°C].
