Description

The QUESTemp°™ 44 3M Heat Stress Monitor offers high quality heat stress monitoring without the hassle of wet-bulb maintenance. This model measures/calculates 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 reporting and time stamping. On board data logging along with Detection Management Software (DMS) allows for analysis of data with charting, graphing and reporting options. The QUESTemp° 44 QT-44 (with Alkaline Battery) includes Standard Accessories, (1) Sensor Bar Assembly w/ Calculated Wet Bulb using Humidity Sensor, and 2″ Style Globe Sensor.

The new 3M Heat Stress Monitor instruments, the QUESTempº 44 and QUESTempº 46, offer traditional heat stress monitoring without the aggravation of maintaining a wet bulb.
Through collaboration with Professor Dr. Thomas Bernard, from the College of Public Health at the University of South Florida, mathematical models were implemented to create a Waterless Wet Bulb calculation through a combination of dry bulb temperature, globe temperature, relative humidity, and air flow. The Waterless Wet Bulb is used to calculate the Wet Bulb Globe Temperature (WBGT) which is a widelyused method to monitor environmental conditions related to heat stress.

 

The QUESTemp° 44/46 data logging area heat stress monitor directly senses three parameters: dry bulb temperature (DB), globe temperature (G), and relative humidity (RH).
It computes the wet bulb (WB), the Wet Bulb Globe Temperature (WBGT), stay times for four possible indices, and the Heat Index (HI) or the Canadian Humidex. Using inputs on the side of the instrument, two additional sensor arrays can monitor up to three locations simultaneously.
On the QUESTempº 46 model, you can measure airflow, in meters per second, by plugging an optional hot wire anemometer sensor into a side jack on the unit.
Determine thermal comfort indices, Predicted Mean Vote (PMV) and Predicted Percent Dissatisfied (PPD), using Detection Management Software (DMS).
