Complicated Heat Stress Measurement - Made Intuitive:

Heat stress management is often viewed as complex and time-consuming. Those assigned this task are commonly intimidated by the calculation of the WBGT (Wet-Bulb Globe Temperature) index used to measure the potential for heat stress. And beyond measurement of WBGT is the question of what to do with the data collected and how to transfer findings into a heat stress management program.

3M Detection Solutions helps simplify heat stress management with the brilliantly intuitive QUESTemp° family of heat stress monitors.
  • QUESTemp° area heat stress monitors measure parameters including tem perature and relativity humidity and compute the Wet Bulb Globe Temperature, the generally accepted value for gauging human heat stress.
  • QUESTemp° II personal heat stress monitor measures a worker’ s bodily response to the environment.
  • 3MTM Detection Management Software allows easy download of data for charting, reporting and interpreting measurements.

The data these instruments provide, along with features designed to make your job easier and supporting 3MTM Detection Management Software, offer safety professionals a powerful solution to help establish a heat stress management program.

The 3M™ QUESTemp° Heat Stress Monitor QT-44 offers high quality heat stress monitoring without the hassle of wet-bulb maintenance. This model measures/calculates the dry bulb, wet bulb and globe temperatures along with WBGT indoors, WBGT outdoors, relative humidity and Heat Index/Humidex.
