The Quest Temp series are used by Industry and Military worldwide, including NATO, to protect from high core body temperature and internal heat damage to vital organs: chosen for their portability, accuracy and reliability.

Heat Stress prevention demands accurate measurement and analysis of heat stress in the workplace. Designed for ease of use the QT-34/36/44/46/48 is extremely rugged with IP54 rated protection for water and dust ingress.

The QT measures and displays Dry Bulb, Wet Bulb and Globe temperatures. A separate, Relative Humidity sensor is also built in and to provide RH measurements. Wet Bulb Globe Temperature, WBGT Index is calculated and displayed. Both, WBGT in and WBGT out, in-door and out-door, is displayed on the QT.

The instrument is available with a 2 inch or 6 inch diameter black globe in accordance with BS EN 27243. Data Logging is built into the QT. Logging frequency is programmable from 1/min up to 1/hour. This allows 10 days or months of logging at 1/hour. Power is supplied from a 9 volt disposable battery giving 140 hours operation. Alternatively NiMH rechargeable battery operation is available giving 300hours operation before re-charge is needed. Mains power can also be provided for continuous, 24/7 operation.The QT is ATEX approved, for use in areas where explosive gas may be present.

The option to measure 'Head-Torso-Ankle weighted average WBGT' is achieved with optional plug-in tri-sensor assemblies. These plug-in assemblies can also be used to provide measurement at three locations with extension cables. Data is viewed on the centrally located instrument.

As well as WBGT measurement the QT-34/36/44/46/48 indicates Heat Index and Humidex measurements.
