Extech HT200 Thermometer
The Heat stress meter measures the Wet Bulb Globe temperature, black globe temperature, humidity, air temperature, damp temperature and dew point. A combination of humidity, temperature, air movement and direct sunlight determines exactly the heat load for the body. The device uses a capacitance sensor for accurate measurement of Wet Bulb Globe Temperature (WBGT), black-globe temperature (TG), relative humidity (%RH), air temperature (TA), wet-bulb (WT) and dew point (DEW). The black ball temperature (TG) monitors the effects of the direct sun radiation on an exposed surface. The product is equipped with an indoor/outdoor area function which WBGT value calculated with or without direct sunlight, acoustic and visual WBGT high and low-alarm function, Min/Max, Data Hold Automatic switch-off function with disable function and battery indicator.This text is machine translated.
