The Texas Electronics, Inc. Model TH-2013-QR Relative Humidity Sensor consists of two major components; the sensing element and the radiation shield. The capacitive sensing element and its signal conditioning electronics are housed in an ABS plastic, IP65 probe-like housing. The element is protected from dust, dirt and debris by a filter and a metal shield. This assembly is mounted inside an all-aluminum radiation shield with a white baked-enamel finish. This shield keeps sunlight from directly hitting the element or the probe housing, as well as providing substantial physical protection from rain, hail, small animals, etc.

The capacitive sensing element can be easily replaced in the field with no calibration needed. The elements are interchangeable with no degradation in accuracy. The quick-release mounting bracket allows for ease in maintaining the unit.
