WBGT WBGT-208 Thermal stress measuring device

• 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

Lutron WBGT-208 Heat Index WBGT Meter

Features Lutron WBGT-208 Heat Index WBGT Meter

• 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.
• Globe temperature measurement use the Pt sensor,high accuracy.
• Fast humidity measuring response time.
• Direct measurement of the radiation effect with a brass black ball in 40 mm dia.
• Sensor protecting mechanism.
• LCD with green light backlight, easy reading.
