Feature
■ Indoor use only!
■ WBGT, stands for wet bulb globe temperature, is an index introduced from three elements related to biological heat balance: temperature, humidity, and heat radiation. It is originally calculated from dry bulb temperature, wet bulb temperature, and black globe temperature.
This device simply calculates WBGT from temperature and humidity based on the following guideline, and shows either one of the four levels of caution.

WBGT | Type of risks in relation to physical activity | Remarks |
Danger (31°C or higher) | Risk during any physical activity | Risk of occurrence is high for the elderly, even when they rest. Avoid going out and stay in a cool room. |
Severe warning (28 to 31°C) | Risk during any physical activity | Avoid direct sunlight outdoors and watch for any rise in room temperature indoors. |
Warning (25 to 28°C) | Risk during moderate to vigorous physical activity | Take adequate rest regularly when exercising or doing vigorous work. |
Caution (25°C or lower) | Risk during very vigorous physical activity | Low in risk basically, but high in risk when doing vigorous exercise or heavy labor. |
