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. POPULAR

| Monitor and control relative humidity and
temperature in building energy management systems with the Series HT
Humidity/Temperature Transmitter. Designed for demanding HVAC/EMCS
applications, the Series HT provides ±3% RH accuracy and ±1% stability
per year. Routine calibration is not required with the fully
interchangeable sensor. Two-wire connections allows easy instillation
directly into air ducts or within a controlled area.

Relative Humidity/Temperature
Transmitter Dual Channel Design for Simultaneous 4 - 20 mA Output Signals - Conduit Housing |
 Service Manual Catalog Page |
 Dimensional Enlargement |

The Model 657C-1 Transmitter features the same circuit design as the 657-1 providing two 4 - 20 mA channels to produce separate output signals for both relative humidity and temperature. However, this model is housed in a tough die cast aluminum protective conduit enclosure with gasketed cover. An internal terminal block is provided for electrical connections. The sensor employed in the 657C-1 features a state-of-the-art integrated polymer film humidity sensor and a thin-film platinum temperature sensor to assure high reliability and rock-solid stability over years of continuous service. Stainless steel probe measures 5/16" x 9 1/10" (0.8 x 23.1 cm) and can be easily mounted to most ductwork using either of the two optional kits below. POPULAR

Model 485 Digital Hygrometer is a versatile, hand-held
instrument for measuring percentage of relative humidity and temperature
in °F or °C. Dew point and wet bulb temperature is derived from
relative humidity and temperature measurements and displayed on the
0.4" LCD. A display Hold key freezes the current temperature and
relative humidity readings for situations where readings fluctuate.
Store up to 25 readings with the non-volatile memory function - ideal
for technicians needing to take multiple readings for later analysis. POPULAR
