Series HU provides quick-response, stable and repeatable temperature and humidity readings accurate within I2%. Operating temperature range for the unit is -30 to 130°f (-35 to 55°c), and relative humidity range is 0 to 100% rh. The transmitter's 4 to 20 ma output signal is fully conditioned and temperature compensated. Employing a polymer capacitance sensor, the transmitter from Dwyer Instruments is available for duct mounting in a NEMA 4 (IP56) cold-rolled steel enclosure.
