Application
Application of 87786 AZ Portable WBGT Data Logger:
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.

FAQ
【FAQ of 87786 AZ WBGT Data Logger】
Q1: Why is the AZ 87786 series globe 75mm instead of the standard 150mm?
A: To enhance portability and response time. All AZ 87786 models use a built-in compensation formula to ensure the 75mm globe readings match the ISO 7243 150mm standard.
Q2: Which WBGT model is best for long-term environmental heat stress research?
A: The AZ 87786 is ideal, as it features automated data logging and PC connectivity, allowing you to record and analyze heat trends over extended periods.
Q3: How do the AZ 87786 visually alert users to heat stress dangers?
A: AZ 87786 feature a smart tri-color backlight system (Green, Yellow, Red) based on the current WBGT level. This allows safety supervisors to instantly identify the risk category from a distance—green for caution, yellow for extreme caution, and red for danger—ensuring immediate action can be taken without reading small digits.
