• Ultra fast response cross-linked bulk poly- mer 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 calibra- tion 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

The HU-224/225 is an extremely fast, stable and accurate humidity transducer designed for harsh environments. The polymer 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-224/225 is temperature compensated for -30°F (-35°C) to +130°F (55°C) operation with negligible error. For space humidity, an aesthetically appealing ABS enclosure which may be flush mounted or fits a standard 2" x 4" handy box is available, and for duct humidity applications, a rugged NEMA-4 (IP-65) steel enclosure with external mounting bracket is also available. Two enclosure types, 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-224/225 the industry’s highest performance, most reliable humidity sensor.
