Extech HT200 Digital Hygrometer, ±3 Accuracy, +80°C Max, 99%RH Max

The FLIR Heat Stress WBGT Meter (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.
