Digital portable WBGT-meter - Heat Index Checker / Heat Stroke Prevention Meter / Heat Stress Meter for measuring of dangerous heat conditions and for prevention of heat stroke on working places or by sportive activities. It is an ergonomic, compact, and rugged instrument designed to monitor heat stress potential of personnel in hot working environments and heat stress in sport.  

   Measures heat index (WBGT), temperature (TG & TA) en humidity (% RH). WBGT index is used for integrated evaluation of thermal environments to manage health care in prevention of heat stroke.

Sport :


> 31

Stop exercises, cancel activities (except special occasions)

28 - 31 Avoid hard exercises, marathon or others which required large amount of heat load
25 - 28 Frequent rest breaks and hydration (drinking of water) is recommended
21 - 25 Hydration (drinking of water) during rest breaks is recommended
< 21 Low risk of heat stroke but proper hydration should be encouraged, drink water is necessary

Sport for children, outdoor activities :


> 29,4

Stop exercises, cancel all athletic activities

26,1 - 28,9 Children who haven't yet acclimated to the heat or who are at higher risk of dehydration and heat-related illnesses should stop playing and get out of the heat
23,9 - 25,9 Frequent rest breaks, cooling off and hydration (drinking of water) is recommended each 15 minutes
< 23,9 Low risk of heat stroke, all activities are allowed but proper hydration should be encouraged, drink water is necessary; continuous checking of heat-related sypmtoms
