Industry-leading Technology and Design
Heat stress prevention begins with the accurate measurement and analysis of heat stress in the workplace. The QUESTempº series of heat stress monitors provides safety professionals with the durable, easy-to-use instrumentation needed to measure and analyze heat stress related exposure levels.

QUESTemp° 44
Key Features
  • Waterless wet bulb

The QUESTemp° 44 Heat Stress Monitor 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. A real-time clock provides accurate reporting with time stamping. On-board datalogging along with optional Detection Management Software (DMS) allows for advanced analysis of data with charting, graphing, and reporting options.

Features and Benefits

  • Measure/calculate dry bulb, wet bulb, and globe temperatures, WBGT indoor/outdoor, relative humidity, and Heat index/Humidex
  • Real-time clock provides accurate reporting with time stamping

 

QUESTemp° 46

Key Features

  • Waterless wet bulb
  • Optional air probe provides air speed data

The QUESTemp° 46 Heat Stress Monitor 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. A real-time clock provides accurate reporting with time stamping. On-board datalogging along with Detection Management Software (DMS) allows for advanced analysis of data with charting, graphing, and reporting options.

In addition, the QUESTemp° 46 includes the ability to measure stay times in order to manage work/rest regimens. Guidance is based on the screening criteria for heat stress as defined in the ACGIH TLV Handbook, U.S. Navy PHEL Charts, U.S. Marine Flag System and EPRI Action Limits. The QUESTemp° 46 also features an optional detachable air probe.

Features and Benefits
  • Measure/calculate dry bulb, wet bulb, and globe temperatures, WBGT indoor/ outdoor, relative humidity, and Heat index/Humidex
  • Real-time clock provides accurate reporting with time stamping
  • Stay time measurement per ACGIH TLV Handbook, U.S. Navy PHEL Charts, U.S. Marine Flag System, and EPRI Action Limits
  • Optional detachable air probe
