QUESTemp QT-32 Heat Stress Monitors

Overview

The rugged, easy to use QUESTemp°™ 32 thermal environment monitor quickly and accurately evaluates the potential for individuals to experience heat stress. It combines WBGT index values with relative humidity measurements to calculate the heat index.

Kit includes QUESTemp°™ 32 unit with 2" style globe sensor and standard accessories.
Real-time readings for wet/dry bulb, globe, WBGT indoor/outdoor, relative humidity and heat index.
Optional remote sensors for up to (3) simultaneously monitored areas.

For remote applications, the QUESTemp°™ 32 can be tripod mounted with the detachable sensor tethered at a distance up to 200 ft (60 m) from the main unit. The QUESTemp° 32 QT-32 ( with Alkaline Battery) includes Standard Accessories, (1) Sensor Bar Assembly, and 2" Style Globe Sensor.
