Series HU  Temperature/Humidity Transmitter

0 to 100% RH, ±2% Accuracy, NEMA 4 (IP56) Enclosure
The ultra-fast Series HU Transmitter provides a stable, repeatable, and accurate means of measuring humidity or both temperature and humidity in the harshest of environments The polymer capacitance sensor is not affected by condensation, fog, high humidity or contaminants. Sophisticated integrated circuits provide a fully conditioned and temperature compensated 4-20mA output signal. For humidity or temperature/humidity control, a rugged NEMA 4X (IP56) fully gasketed duct mount enclosure is available or for monitoring space humidity, choose the ABS plastic wall mount enclosure. Units also feature non-interacting zero and span adjustments, short circuit protection and reverse polarity protected output.
