Sper Scientific 801038 WBGT Meter with Color-Coded LCD
Takes the guesswork out of heat stress calculations.
This unique heat stress meter features bright multi-color LCD backlights corresponding to OSHA’s heat stress alert levels. This visual alert system can be seen at a distance allowing management and workers to be instantly aware when the heat index enters potentially dangerous zones. These features, combined with the optional audible alarm help to mitigate the risk of heat-related injuries in the workplace. Calculates heat stress values for direct sunlight and shade and displays humidity, maximum and minimum ambient (TA) and black globe (TG) temperatures. Also indicates low battery and a hold function. 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 complete with clear instructions, integrated tripod screw and 4 AAA batteries. N.I.S.T. Traceable Certificate of Compliance available (for RH & Air Temperature only).
