QUESTEMP
HEAT STRESS MONITORS
Simplify your heat stress management with the intuitive QUESTemp Series Heat Stress Monitors™.
These monitors measure parameters including temperature and relative humidity, and compute
the Wet Bulb Globe Temperature (WBGT).
Features and Benefits
§  Utilizes WBGT sensing technology; the standard for heat stress management
§  Proven traditional wet bulb sensing technology available on QUESTemp models 32, 34 and 36
§  Waterless wet bulb QUESTemp models 44, 66, 48N eliminate daily maintenance
§  Convenient stay time parameters per multiple standards help determine work-rest ratios
§  IP 54 ingress rating helps protect unit from exposure to dirt, dust, oil and water
§  Designed to withstand the rigors of everyday use in demanding environments
