TSI QUESTemp® QT44, QT46, and QT48N Waterless Wet Bulb Heat Stress Monitors

QUESTemp 44 and 46 heat stress monitors simply heat stress management efforts by providing users with real-time guidance on stay times and work/rest regimens with a newly engineered waterless wet bulb sensor. The QUESTemp 48N is specifically engineered for Department of Defense Ashore and Afloat operations, and is built for working environments where daily instrument upkeep is difficult. A high-quality humidity sensor and a proprietary algorithm perform the calculation of WBGT values, eliminating the hassles of daily wet bulb maintenance.

The U.S. Center for Disease Control has produced "Protecting Yourself from Heat Stress" to help you identify the symptoms of heat stress illnesses, and steps you can take to reduce heat stress issues in your workplace.
