Measure heat stress in the field

Government organizations such as OSHA have set recommended heat stress limits for various activities. WBGT (Wet Bulb Globe Temperature) provides the most accurate determination of the heat stress index based on the cumulative effect of air temperature, air movement, relative humidity, and radiant heat. WBGT Heat Stress Meter 800036 is a light-weight meter compact enough to carry anywhere to avoid heat exhaustion in public health, sports, military and industrial activities. Highly accurate readings with a typical response time of only 15 seconds. Provides settings for both indoor and outdoor activity and includes an audible alarm, adjustable to your WBGT threshold. One of the many advantages of the WBGT Heat Stress Meter 800036 is its ability to stream data directly to a computer to log real time information. In order to connect this model to a computer to stream data, you will need the USB Cable 840054 and Data Acquisition Software 840052. Comes with tripod screw and has the ability to connect with a computer with the proper accessories. N.I.S.T. traceable certificate of compliance available (for RH & Air Temperature only).
