HU-227 Series Information

  • Ultra fast response
  • Proprietary hydrophobic and oleophobic ePTFE filter
  • Conformal coated and moisture sealed elec‑tronics
  • Rugged steel enclosure
  • Two temperature compensated humidity output versions
  • Conforms to EMC and RoHS standards
The HU‑227 Outside Air Humidity and Temperature Sensor is designed to handle 100% condensing humidity. The electronics are moisture sealed with an acrylic coating, and the sensing element is protected with an ePTFE (expanded Teflon) filter media. The unit can be directly mounted inside fresh air hoods of air handlers or underneath roof overhangs of any building. The sensor can also be installed inside the air handler fresh air duct. 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. The rugged NEMA‑4 (IP‑65) rated steel enclosure, thick‑walled aluminum probe and gasket sealed cover offer a reliable solution for factory‑mounted applications. Each HU‑227 is calibrated at multiple points in a NIST traceable calibration chamber to meet or exceed (‑+2%) RH or (‑+3%) RH accuracy. Units are temperature compensated over ‑30 F (‑35 C) to +130 F (55 C) temperature range operation with negligible error. HU‑227 is available with more than 16 types of interchangeable NTC thermistors, precision platinum, nickel or balco RTDs for universal compatibility.
