Heat Stress Wet Bulb Globe Temperature Meter - 

HT200 is a heat stress WBGT meter. This heat stress WBGT (wet bulb globe temperature) meter accurately determines the heat stress level (how hot it feels outside) by factoring a combination of humidity, temperature, air movement, and direct solar radiation. These factors all affect how hot our bodies get, as well as our ability to cool down. It's perfect for monitoring the heat index on hot humid days to prevent heat stroke during road or building construction, outdoor activities, sporting events, or in the workplace.
