AZ Instruments
Handheld WBGT Heat Stress Meter
with wind speed measurement
(Model No.: AZ-87785)
Heat Stroke Prevention Meter
Wind speed value makes your WBGT more close 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.
