The HU-225 is an extremely fast, stable and accurate humidity/temperature transducer designed for harsh environments. The polymer humidity capacitance sensor is protected with an ePTFE (expanded Teflon) filter media. The Teflon protected cross-linked capacitive humidity sensor is not affected by prolonged exposure to condensing humidity, harsh environments, contaminants, fog or other extreme environmental conditions. Each unit is individually calibrated in an environmental test chamber to meet or exceed NIST traceable ±2% or ±3% accuracies. The HU-225 is temperature compensated for -30ºF to 130ºF (-35°C to 55°C) operation with negligible error. The HU-225 humidity/temp transducer has an aesthetically appealing ABS enclosure, which may be flush-mounted or fits a 2" by 4" handy box. Field selectable outputs, fully temperature compensated NIST traceable accuracy, non-interacting zero and span adjustments, short circuit and reverse polarity protected output, and a liberal five year warranty are some of the features which make the HU-225 the industry’s highest performance, most reliable humidity/temperature sensor.
Features:
Ultra fast response cross-linked bulk polymer capacitive sensing element
Proprietary hydrophobic and oleophobic ePTFE filter to protect the sensing element from condensation, fog, salt air, pollutants and other contaminants
Rugged steel enclosure and thick-walled aluminum probe rated NEMA-4 (IP-65) to withstand weather extremes
NIST traceable ±2% RH or ±3% RH calibration accuracy
Two temperature compensated output versions, 4-20 mA 2-wire or field selectable 0-5 VDC/0-10 VDC
Conforms to EMC and RoHS standards
Two enclosure types: NEMA-4 (IP-65) duct mount or aesthetically appealing ABS plastic wall mount
