The TSI Quest QT range of Heat Stress Monitors comprises of six versions + six version variants which can measure and compute a range of different parameters including WGBT (indoor) index and WBGT (outdoor) index. The QT44, QT46 and QT48N versions have a waterless wet bulb sensor designed for working environments where daily instrument maintenance is difficult.

Features

• QT32, QT34 and QT36 - Natural wet bulb models
• QT44, QT46 and QT48N - Waterless wet bulb models
• Utilises WBGT sensing technology; the standard for heat stress management
• Traditional wet bulb sensing technology
• Tripod mount
• Data logging (All models except the QT32 version)
• 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
• Optional tri sensor probes available for measuring parameters such as head-torso-ankle weighted average WGBT
