The Wet Bulb Black Bulb Temperature (WBGT) Index Tester 2020-2 has important application value in health field testing, supervision and law enforcement. The Wet Bulb Black Bulb Temperature (WBGT) Index Tester is mainly used to evaluate and monitor the thermal environment of the workplace, especially in the places where the hot or humid environment works, such as steel mills, glass products factories, power plants, coal mines, etc. By measuring and calculating the WBGT index, it is possible to understand the heat load of the working environment and thus assess whether the working conditions may have an adverse effect on the health of workers.
The Wet Bulb Black Bulb Temperature (WBGT) Index Tester 2020-2 is a basic parameter used to measure and evaluate the heat load of the human body in contact with the working environment. This index takes into account four factors: air temperature, wind speed, air humidity and radiant heat, and is an important tool for preventing heatstroke (heat stroke) and other heat-related diseases.
The working principle of the WBGT index tester is based on a certain mathematical formula to calculate the WBGT index. In the absence of indoor and outdoor solar radiation, the calculation formula is: wbgt = 07 * tnw + 0.3*TG, where TNW is the natural wet bulb temperature and TG is the black bulb temperature. In the case of outdoor solar radiation, the calculation formula is: wbgt = 07 * tnw + 0.2 * tg + 0.1*ta, where ta, is the air dry-bulb temperature.
When using a Wet Bulb Black Bulb Temperature (WBGT) Index Meter, the required data can be obtained by direct measurement or by using a dry bulb thermometer, a natural wet bulb thermometer, a black bulb thermometer, etc., in the same place. The measured data can help us determine the heat load of the working environment, so that we can take corresponding preventive measures, such as adjusting working hours and providing heatstroke prevention and cooling equipment, etc., to ensure the health and safety of workers.
