Duct Temp and Humidity Sensor

Humidity control is an important aspect of any climate control system. Therefore, humidity sensors must be both accurate and dependable. Automated Logic’s humidity sensors are prescreened for accuracy, eliminating the need for field calibration. The Duct Units are also extremely dependable, with a watertight enclosure.

Automated Logic Duct Humidity Sensors feature medical-grade closed cell foam to seal the probe insertion hole and to absorb vibration. Mounting tabs allow for easy installation directly to the wall of the duct. All Duct Units have etched Teflon leadwires and are built to withstand high humidity and condensation and perform under real world conditions.
