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.
AZ87782 Handheld type WBGT meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
