TSI Quest QUESTemp 46
The QUESTemp° 44/46/48N utilizes a waterless wet bulb sensor 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.
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.
- Utilizes WBGT sensing technology; the standard for heat stress management
- Waterless wet bulb sensing technology eliminates daily maintenance
- 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
