Heat Stress Monitors

Heat stress management is often viewed as time-consuming and complex. Simplify your heat stress management with TSI’s intuitive QUESTemp° Series Heat Stress Monitors.

QUESTemp° Heat Stress Monitors are designed to quickly and accurately evaluate potential heat stress environments. These instruments deliver high-performance monitoring using Wet Bulb Globe Temperature (WBGT) sensing technology, the standard for heat stress management, and the calculation of a WBGT Index value.

Our monitors allow you to eliminate daily maintenance. Convenient stay time parameters per multiple standards help determine work-rest ratios, and IP 54 ingress rating helps protect units from exposure to dirt, dust, oil and water.

Our monitors are designed to withstand the rigors of everyday use in demanding environments, providing reliable monitoring throughout the life of the product.
