Special device from Easy Test

Quantity:

Measurement:
* Wet bulb globe temperature ( WBGT ) @ Indoor/Outdoor
* Black globe temperature ( TG )
* Air temperature ( TA )
* Wet bulb temperature ( WB )
* Humidity
* Dew point temperature
WBGT formula * Wet bulb globe Temp.:
* Indoor/Outdoor and no sun : WBGT = ( 0.7 x WB ) + ( 0.3 x TG )
* Outdoor and full sun : WBGT = ( 0.7 x WB ) + ( 0.2 x TG ) + ( 0.1 x TA )

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 ) in establishing 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..
Adjustable WBGT alarm setting, if the WBGT value over the alarm threshold, the buzzer will sound along with the flashing Display.
Using to control and monitor of physical activity in hot environment to limit the danger of heat related injuries.
