with wind speed measurement
(Model No.: AZ-87785)

Heat Stroke Prevention Meter

Wind speed value makes your WBGT closer to real climate thermo impact!

The Wet Bulb Globe Temperature (WBGT) is a measure of the Heat Stress in direct sunlight, which takes into account: temperature, humidity, wind speed, sun angle, and cloud cover (solar radiation). The measurement by WBGT Checker had been considered as a good element for monitoring the outdoor activities and Prevent people to get Heat Stroke. Military agencies, OSHA, and many nations use the WBGT as a guide to managing workload in direct sunlight.
