Duct humidity sensors

HYGRASGARD® duct humidity sensors measure reliably and precisely the relative humidity and/or temperature in the ventilation duct, in refrigeration, air conditioning and clean room technology and convert the measured variables into a standard signal of 0-10 V or 4...20 mA. Many instrument groups can also display other parameters: relative humidity [% r. h.], absolute humidity [g/ m³], mixing ratio [g/ kg], dew point temperature [°C], enthalpy [kJ/ kg] and ambient temperature [°C].
