    Wet Bulb Globe Temperature WBGTDietitians of Canada state that you can lose anywhere from 0.3L to 2.4L of sweat per hour depending on the weather and your activity level. Dehydration is a serious contributing factor to heat stress.

    WBGT Monitors will accurately measure temperatures that the body is experiencing by taken into account temperature, radiant heat, evaporative potential (relative humidity), and air movement.

    You may need to apply correction factors for clothing above single layer pants and long sleeve shirt and consider the employee’s work load.
