Description： * WBGT (wet-bulb globe temperature) was developed as a monitoring basis at US military training　camps and became widespread for the use in workplaces and sports situation It is suggested in 　the international standard ISO 7243, OSHA (US Occupation Safety), Japan Society for Occupational　Health and the SMA (Sports Medicine Australia) to establish the permissible heat exposure limits in　health, sports or other physical activities.* Measurement : WBGT value (Indoor/Outdoor Wet bulb globe temperature), Black globe　temperature, Humidity, Air temperature, Wet bulb temperature, Dew point Temp..* Measurement function :　1. Wet bulb globe temperature (WBGT):　　　Indoor : 0 oC to 59 oC.　　　Outdoor : 0 oC to 56 oC.　2. Black globe Temp (TG) : 0 to 80 oC.　3. Air temperature (TA) : 0 to 50 oC.　4. Wet bulb temperature (WB) : -21.6 oC to 50.0 oC.　5. Humidity : 5 % to 95 % R.H..　6. Dew point Temp. : -25.3 oC to 48.9 oC.* Unit : oC,oF, Resolution : 0.1 degree.* Adjustable WBGT alarm setting with buzzer sound output.* Control and monitor of physical activity in hot environment to limit the danger of heatrelated　injuries.* Globe temperature measurement...
