Unaffected by heat, cold, condensation, fog, high humidity, or encompassing contaminants, the Series HU temperature/humidity transmitter offers quick, stable, repeatable, and accurate (±2%) temperature and humidity readings, says the company. Operating temperature range for the unit is -30Â° to 130Â°F (-35Â° to 55Â°C). Relative humidity range is 0 to 100% rh. The transmitter’s 4 to 20 mA output signal is fully conditioned and temperature-compensated, the company says. Humidity-only models are also available.
