Anyone who has stood under welcome shade adjacent to a sizzling parking lot understands that these conditions must be evaluated exactly where peoples’ activities are taking place.  The most common composite measurement used to determine appropriate exposure to heat stress conditions is Wet Bulb Globe Temperature or “WBGT.”\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0209\/2718\/files\/unnamed_large.png?v=1486651682\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0209\/2718\/files\/unnamed_1_large.png?v=1486651755\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow Does the Kestrel 5400 Work?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe Kestrel 5400 uses a 1-inch black globe to gather information about the environment, which isn't possible with current Kestrels. As is true with the original Wet Bulb Globe Temperature apparatus, a temperature sensor is installed inside the globe that will measure the temperature inside. The temperature inside the globe is a function of the ambient air temperature, solar insolation, and wind speed.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAs one can imagine, a sunny day will make the globe hotter because it's painted black, and colder ambient temperatures will have a tendency to cool off the globe. Lastly, the wind will cause the globe to get closer to the ambient air temperature because it will carry heat away from the globe when the air is cooler, or increase heat transfer to the globe if the air is warmer than the globe.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe Kestrel must sit out for a period of time to allow the globe to adjust to true atmospheric conditions; we recommend a minimum of 7-10 minutes. The globe temperature is then taken into account along with other measurements, such as ambient temperature, humidity, and pressure, to calculate more meaningful measurements, such as Wet Bulb Globe Temperature and Thermal Work Limit.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003e\u003cb\u003eIndoor Use\u003c\/b\u003e\u003c\/h6\u003e\n\u003cp\u003e\u003cspan\u003eReading the WBGT is important even in indoor settings where heat stress is a concern.  The Kestrel has an 'indoor' setting on the WBGT setting which basically turns off the function of taking into account the direct solar radiation from the sun.  It's important to place the Kestrel in a representative area of the conditions that the workers face.  Remember, wind plays a factor in WBGT, so a vane mount can be used indoors as well.  In the case of a ceiling fan, if the Kestrel doesn’t pick up the ceiling fan, then you are essentially getting the “worst case” WBGT readings which is not actually a bad thing.  If the airflow is pretty strong from the fan and you want to have that factored in, you could mount the Kestrel sideways (vs vertical) so the impeller picks up the wind more realistically.  You can use the \u003c\/span\u003e\u003ca href=\"https:\/\/kestrelmeters.com\/collections\/kestrel-tripods\/products\/ultraclamp-2-5\" target=\"_blank\"\u003e\u003cspan\u003eClamp\u003c\/span\u003e\u003c\/a\u003e\u003cspan\u003e to achieve this.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003e\n\u003cb\u003eWhy Use WBGT as a Heat Stress Indicator vs. just using the Heat Index?\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003e\n\u003c\/h6\u003e\n\u003cp\u003e\u003cb\u003eWet bulb globe temperature\u003c\/b\u003e\u003cspan\u003e (\u003c\/span\u003e\u003cb\u003eWBGT\u003c\/b\u003e\u003cspan\u003e) is based on an equation that uses a combination of environmental elements to calculate the reading.
