Casella Microtherm WBGT Heat Stress Monitor

An overall estimation of the heat stress levels on a body can be measured using the Wet Bulb Globe Temperature (WBGT) Index. This combines the results from three temperature sensors into a single calculated value that may be compared with reference values depending upon the specific work regime. The Casella Microtherm Heat Stress Monitor has Audible & visual warning of level excedances RH% and dewpoint calculation.

Windows PC software for setup and download of results from memory The WBGT meter measures simultaneously from three PRTD sensors for wet bulb (tnw), dry bulb (ta) and globe (tg) temperatures. Sensors are manufactured to high accuracy.
