Outside Air Temp and Humidity

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 outside air units are also extremely dependable, with a watertight (IP66), UV-resistant polycarbonate enclosure.

Automated Logic outside air temperature and humidity sensors have etched Teflon™ leadwires and are built to withstand high humidity and condensation and perform under real world conditions. This is especially important in an outside air sensor which can be exposed to rain, snow, and large temperature swings.
