Application

The Wet Bulb Globe Temperature (WBGT) is a composite temperature used to estimate the effect of temperature, humidity, wind speed and solar radiation on humans.

The 8778 AZ Portable WBGT Meter could measure the Heat Stress in direct sunlight. The WBGT measurement had been considered as a good element for monitoring the outdoor activities and Prevent people to get Heat Stroke.

It is used by industrial hygienists, athletes and military to determine appropriate exposure levels to high temperatures. Military agencies, OSHA and many nations use the WBGT as a guide to managing workload in direct sunlight.

The 8778 AZ Portable WBGT Meter could measure the indoor/ outdoor WBGT, TA/TG and Humidity. User could download the real time value via USB cable to PC. It could be applied for measuring the WBGT value in construction, iron and steel foundries, bricks-firing plants, glass facilities, boiler rooms, mining sites, army training, marathon, beach activities and so on.

The 8778 AZ Portable WBGT Checker designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring.
