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 Handy 87786 AZ WBGT Data Logger could measure air temperature, globe temperature, and humidity to give heat stress index for using in control of physical activity in hot environment to limit the danger of heat-related injuries.
The 87786 AZ Portable WBGT Data Logger can show the different backlight color to distinguish the different temperature value/level. There are 4 kinds of WBGT indicator as follows, 1. Green back light: 26.7~29.4℃ 2. Yellow back light: 29.4~31℃ 3. Red back light: 31~32℃ 4. Red Flashing back light: above 32.2℃ So the 87786 AZ Portable WBGT Data Logger could be the best tool for monitoring the outdoor activities and Prevent people to get Heat Stroke.
The 87786 AZ Portable WBGT Recorder could be operated by industrial hygienists, athletes and the military to determine appropriate exposure levels to high temperatures. Military agencies, OSHA and many nations use the WBGT as a guide to manage workload in direct sunlight.
User could record and download the real time value of 87786 AZ Portable WBGT Recorder via mini USB cable to PC for data analysis. There is no need to install USB driver or software before operating logging function. It could be operated as the USB memory flash drive easily on PC. And there is a tripod hole on the bottle of 87786 AZ Portable WBGT Recorder. User could use the tripod to hold the device vertically for long term use. 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.
87786 AZ Portable WBGT Recorder was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring.
