Battery Operated Heat Stress Monitor

The QUESTempº Series area heat stress monitors are designed to help quickly and accurately evaluate potential heat stress environments. These rugged instruments deliver high performance monitoring through WBGT (Wet Bulb Globe Temperature) sensing technology and the calculation of a WBGT Index value. An optional air probe enables the calculation of PMV/PPD thermal comfort indices. These innovative instruments are designed for the rigors of the workplace, with easy-to-use features, intrinsic safety certification* and advanced reporting capabilities.
