Details

The QUESTempº 44/46/48N Waterless Wet Bulb Area Heat Stress Monitors utilises its waterless wet bulb sensor that is designed for working environments where daily instrument upkeep is difficult.

A high-quality humidity sensor and proprietary algorithm perform the calculation of the Wet Bulb Globe Temperature (WBGT) values, eliminating the hassle of daily wet bulb maintenance.

Features and Benefits:

▪ Uses a proprietary algorithm to calculate the WBGT; eliminates daily wet bulb maintenance
- ▪ Convenient stay time parameters per multiple standards help determine work-rest ratios
- - ▪ IP 54 ingress rating helps protect the unit from exposure to dirt, dust, oil and water
  - - ▪ Designed to withstand the rigours of everyday use in demanding environments
