WBGT Heat Stress Monitor Model SK-160GT
This is a Wall-mount/desk-top type instrument that indicates the indoor WBGT Index and the guideline with four warning levels and measures temperature and humidity. When the measured value exceeds the set WBGT index, buzzer sounds and LED lights. Atomic clock is equipped.
This instrument is indoor use only.
The wet bulb globe temperature (WBGT) index integrates the three factors of air temperature, humidity and radiation heat, each of which greatly affects the heat balance of the human body. The index is normally obtained using the dry, wet and black bulb temperature measurement values.
Measurement of wet or black bulb temperature requires considerable expertise, and the equipment handling and location are limited.
The unit calculates the WBGT index by using the measured temperature and humidity, in accordance with the "Guidelines to prevent heat disorder in daily life" of the Japanese Society of Biometeorology.
The WBGT index is low when the air temperature and humidity are low, while it is high when the air temperature and humidity are high.
The risk of heatstroke increases with the WBGT index. Thus, the determined WBGT index can be used as a guideline for preventing heatstroke.
