Heat Stress Monitors feature waterless wet bulb calculation.

Press Release Summary:



Incorporating Waterless Wet Bulb sensor, QUESTemp°44 and 46 evaluate indoor and outdoor environmental conditions for potential to cause heat stress or heat-related injuries. Both portable instruments measure/calculate dry bulb, wet bulb, and globe temperatures along with WBGT indoors, WBGT outdoors, relative humidity, and Heat Index/Humidex. In addition, QUESTemp° 46 includes ability to measure stay times in order to manage work/rest regimens.



Original Press Release:



New Heat Stress Monitor Featuring Waterless Wet Bulb Calculation



Oconomowoc, WI - 21 November 2008- Quest Technologies is pleased to announce the addition of the QUESTemp°44 and 46 to our portable heat stress instrumentation series. These instruments are used to evaluate indoor and outdoor environmental conditions for the potential to cause heat stress or heat-related injuries. The QUESTemp° 44 and 46 incorporate a Waterless Wet Bulb sensor, which offers traditional heat stress monitoring without the aggravation of wet bulb maintenance.

Waterless Wet Bulb - Eliminates the Hassle of Wet Bulb Maintenance

The Waterless Wet Bulb calculation was created in conjunction with Dr. Thomas Bernard, Professor in the College of Public Health at the University of South Florida. Using this method, an algorithm utilizes temperature and humidity readings to calculate the wet bulb equivalent temperature and to compute the WBGT. Wet-bulb globe temperature (WBGT) is a recognized method to monitor environmental conditions related to heat stress. The Waterless Wet Bulb calculation ensures accurate WBGT readings without the maintenance of adding water to the wet bulb sensor.

High Quality Heat Stress Management

The QUESTemp° 44 and 46 heat stress monitors provide simplified heat stress management with high quality product features. Both models measure/calculate the dry bulb, wet bulb, and globe temperatures along with WBGT indoors, WBGT outdoors, relative humidity and Heat Index/Humidex. A real time clock provides accurate reporting with time stamping. On board data logging along with QuestSuite Professional II software allows for advanced analysis of data with charting, graphing and reporting options.

Stay Time Measurement

In addition, the QUESTemp° 46 includes the ability to measure stay times in order to manage work/rest regimens. Guidance is based on the screening criteria for heat stress as defined in the ACHIH TLV Handbook, U.S. Navy PHEL charts, U.S. Marine Flag system and EPRI Action Limits. The QUESTemp° 46 also features an optional detachable air probe.
