New Heat Stress Monitor Featuring Waterless Wet Bulb Calculation

摘要

Quest Technologies (USA) 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. 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.
