QUESTemp 36


TSI Quest QUESTemp 36

The QUESTemp° 32/34/36 Area Heat Stress Monitors are designed to quickly and accurately evaluate potential heat stress environments. These instruments deliver high-performance monitoring through Wet Bulb Globe Temperature (WBGT) sensing technology and the calculation of a WBGT index value.
  • 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.
LanguagesEnglish, French, Spanish, Italian, German.
HousingDesigned water resistant to a light rain or mist. If rain is frequent, best practice would be to remote the sensor bar and keep the instrument sheltered.
