Ducted/ Wall Mounted Humidity Sensor Transmitters efficiently detect and transmit data using digital signals. These Humidity Sensor Transmitters are fitted with processor which is able to detect varying low and high temperature and humidity. These Humidity Sensor Transmitters can be easily ducted and wall mounted in strategic places desired. Ducted/ Wall Mounted Humidity Sensor Transmitters utilize moronic hygrometer capacitance sensor dew point and wet bulb temperature to provide accurate with long term stability results.
