The corporate obligation of heatstroke will start to be enforced on June 1, 2025. Working in environments above 31 degrees Celsius or above WBGT28 and may have more than a certain amount of time. There is an increase of heatstroke accidents in schools and welfare facilities, and countermeasures are urgent in the field.
The WBGT (Heat Index) is an indicator that focuses on the heat interaction between the human body and the outside air. It incorporates 3 of the temperature of the environment, such as the humidity, which has a large effect on the heat balance of the human body.
What is black ball? ]
The black bulb can measure the radiant heat caused by sunlight or reflecting the ground, and numbers the temperature you actually feel the body.
This allows you to understand the risk of heatstroke, whether indoors or outdoors, helping you to manage safety during exercise or work.
Radiant heat: direct sunlight or reflected heat from the ground.
The Ministry of the Environment also recommends a heatstroke index with black bulbs.
What is the difference between the thermometer? ]
A general thermometer can only measure "temperature", but this product will evaluate the temperature, humidity, and sunlight (radiant heat) and display the danger of the heat (WBGT).
For example, during exercise or outdoor activities, the strain on the body can be greatly affected by sunlight and humidity.
This is a big difference in how it is to see the "real heat" and judge the risk of heatstroke.
