Reading outdoor air where condensation is the norm rather than the exception, this outside air temperature sensor seals a 10,000 ohm Type II thermistor inside a weatherproof housing rated for cold storage and high dew point service. A sun shield keeps direct radiation off the sensing element, so the reading reflects the air temperature rather than the temperature of the enclosure.

The ACI Thermistor Outside Air Series features a weather proof European Style Plastic enclosure with twist off cover and water tight cord grip fitting. The sensing element contains two, 14 inch 22 AWG Etched Teflon colored lead wires to differentiate the many different sensor types. All sensors in this series are manufactured using ACI's proven double encapsulation process to eliminate the effects of moisture upon the sensors as well as to increase the thermal response time using our high quality, thermally conductive epoxy. The outside air sensor is a single point sensor designed to be mounted under an eave or on the North side of a building in a shaded location.
