Ideal for room and greenhouse monitoring, this combined humidity and temperature transmitter comes complete with well-vented housing. Versatile and accurate, this transmitter features a 3% accuracy, a field-selectable temperature range, and a universal current/voltage output for RH and temperature.
Ideal for room and greenhouse monitoring, this combined humidity and temperature transmitter comes complete with well-vented housing. Versatile and accurate, this transmitter features a 3% accuracy, a field-selectable temperature range, and a universal current/voltage output for RH and temperature.
Well-vented to provide airflow across the sensor to improve measurement accuracy, this wall-mount transmitter measures humidity, temperature, and dew point. By using a capacitive polymer sensor that completely recovers from 100% saturation, humidity and the dew point are measured accurately.
