TSI Quest QUESTemp



The QUESTemp° 32/34/36 Area Heat Stress Monitors are designed to quickly and accurately evaluate potential heat stress environments.

The QUESTemp° 44/46/48N utilizes a waterless wet bulb sensor designed for working environments where daily instrument upkeep is difficult.
QUESTemp 32/34/36
  • Utilizes WBGT sensing technology; the standard for heat stress management
  • Traditional wet bulb sensing technology
  • 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

MeasurementsGlobe, dry bulb, wet bulb, WGBTin, WGBTout, WGBT weighted average (if 3 sensor sets), relative humidity, Heat Index, Humidex.
Temperatures given in Celsius or Fahrenheit.
Data LoggingRecords and prints all measurements at user selected interval of 1, 2, 5, 10, 15, 30, or 60 minutes. 128K bytes of data memory.
