HEAT STRESS MONITOR ( WBGT ) SK-150GT PT OCTA PRIMA LESTARI

  The SK-150GT is a handy type instrument that can measure temperature, humidity and globe temperature to approximate the WBGT index ( * ) .

 This can be used as a guide for preventing heat related illness and estimating heat stress of working and activity related environments.

  WBGT Index :  The process for determining the WBGT ( Wet Bulb Globe Temperature) is described in ISO 7243 / JIS Z8504, Hot Environments

 - Estimation of the Heat Stress on Working Man, based on the WBGT Index. The WBGT index is a sensory temperature which can be calculated from wet bulb temperature, globe temperature ( radiation heat) and dry bulb temperature. It is necessary to set the measuring ambient before starting since different calculation is needed depending on its measuring ambient.

 ( 1)       Indoor ( IN) : when measuring indoor or outdoor away from direct sun light.  WBGT Index( ° C) = 0.7 x Wet Bulb Temperature( ° C) + 0.3 Globe x Temperature( ° C)

 ( 2)       Outdoor ( OUT) : when measuring outdoor, under direct sun light. WBGT Index( ° C) = 0.7 x Wet Bulb Temperature( ° C) + 0.2 x Globe Temperature( ° C) + 0.1 × Dry Bulb Temperature( ° C)

 
 Heat Stress :

 Heat stress is a condition that temperature regulation function decreases by high temperature ambient. This could cause a heat related illness and even ultimately death. The risk can be reduced by observing the surrounding ambient and by being aware of precautions of heat stock such as overheating and dehydration.

  FEATURES     :

  Alarm: The alarm is triggered when the measured WBGT value reaches the set value. 
  HOLD function, MAX/ MIN function 
 Measuring ambient of WBGT index can be set. 
  Auto power-off ( in 20 min.) 
  Carrying case for damage prevention and storing of the instrument.
