QUESTemp° Series Monitors are designed to provide you with maximum value. In all QUESTemp° Thermal
Environment Monitors a dry bulb sensor measures ambient temperature; a wet bulb sensor takes into account
evaporative cooling, giving an indication of the effects of humidity on an individual; and a globe sensor provides
an indication of the radiant heat exposure on an individual due to either direct light or hot objects in an
environment. QUESTemp° Thermal Environment Monitors convert these measurements to a simplified, singlenumber
Indoor and Outdoor WBGT Index. This index can then be used in conjunction with guidelines developed
by ACGIH, U.S. Navy, EPRI, ISO and others. Each of these guidelines includes considerations for real-life variables
such as activity levels or clothing types worn. Using QUESTemp° Thermal Environment Monitors in conjunction
with any one of these guidelines enables you to determine appropriate work/rest regimens or stay times for
workers in situations where heat stress is a life safety and liability risk.
