Application

Application of 87784 AZ Wearable WBGT, Heat Index Meter:
The 87784 AZ Wearable WBGT HI Checker can measure the air temperature, globe temperature, heat index 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 Wet Bulb Globe Temperature (WBGT) was developed as a monitoring basis at US military training camps and became widespread for the use in workplaces and sports situations. The WBGT is a measure of the Heat Stress in direct sunlight.

The heat index was developed by the US National Weather Service to help people avoid heat illness. Prolonged exposure and/or physical activity at a high heat index is likely to lead to sun stroke, heat cramps, heat exhaustion and even death. However, please be aware that heat index is not an exact science. The values reached are approximations. Ultimately, the final decision of whether or not to exercise or work belongs to the individual, athletic trainer or employer…

It is suggested in an international standard ISO 7243 and many governments such as OSHA (US Occupational Safety & Health Administration), SMA (Sports Medicine Australia) and Japan Society for Occupational Health in establishing the permissible heat exposure limits in occupational health, sports or other physical activities. The applications of the heat index can be in construction, iron and steel foundries, bricks-firing plants, glass facilities, boiler rooms, mining sites, army training, marathon, beach activities and so on.

The 87784 AZ WBGT Heat Index Meter has a small black ball, which could be carried easily. And the small black ball has a specific angle, so you would not need to worry about human temperature affect the meter’s accuracy. The measurement by 87784 AZ WBGT HI Checker could be a good element for monitoring the outdoor activities and Prevent people to get Heat Stroke.

AZ 87784 wearable WBGT +Heat Index Checker was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring.
