This wall-mount humidity and temperature transmitter monitors indoor climate control and building performance validation. It measures 0 to 100% RH and -40 to 140°F (-40 to 60°C), with internal dip switches to select temperature units and humidity or dew point output. The IP20 well-vented housing improves airflow across the capacitance polymer RH sensor that completely recovers from 100% saturation.
