The QUESTemp° 34 Thermal Environment Monitor is the apparatus used to determine the Wet Bulb Globe Temperature at Fort Bliss. The monitor is located on Biggs Army Airfield. The QUESTemp°34 provides quick and accurate WBGT measurements for assessing environmental heat stress. This monitor measures and displays dry bulb, wet bulb, and globe temperatures while calculating and displaying indoor and outdoor WBGT indices. The QUESTemp° 34 also incorporates a relative humidity (RH) sensor. This integral RH sensor enables the QUESTemp° 34 to measure and display % RH while calculating and displaying heat index. The QUESTemp° 34 is extremely sensitive to temperature changes.

WBGT readings will vary from one location to another due to several factors. The type of WBGT monitor in use, calibration of equipment, operator´s knowledge of the equipment, site location/environment (i.e. shady, windy, in direct sun light, next to large body of water, etc.) are all factors that will come into play when taking WBGT readings. With that being said, the WBGT readings depicted on this website may differ from the WBGT readings at other locations. The WBGT readings depicted on this website should be used as a guideline only. As a recommendation, Commanders should set up their unit´s WBGT monitoring device(s) via their Field Sanitation Teams to determine the WBGT index in their respective locations.
