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
