Wet Bulb Globe Temperature Heat Stress Meter, Backlit LCD Display, 32 to 138 deg F, 1 to 99% RH, +/-1.8 deg F, +/-3% RH

Extech’s HT200 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.The heat stress WGBT meter which enables accurate measurements for wet bulb globe temperature (wgbt), black globe temperature (tg), humidity (%rh), air temperature (ta), wet bulb (wt) and dew point (dew). Heat Stress Index measures how hot it feels when humidity is combined with temperature, air movement and radiant heat.
