Heat Stress Monitor

Model No : QT032 , QT034 , QT036

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.

QUESTEMP0 Area Heat Stress Monitor has two Catagories as follows :
1. QUESTEMP0 Natural Wet Bulb Models
2. QUESTEMP0 Waterless Wet Bulb Models

Key Features

• Models with Intrinsic Safety Certification.
• Long Battery life & Robust construction.
• Data Logging capabilities and enhanced reporting and measurement.
• Convenient stay time display per multiple standard.
• Multilingual Display (English, French, German, Italian, Spanish).
• Download data to Detection Management Software DMS for analysis and data management.
• Optional remote sensor bar allows for simultaneous monitoring of up to three areas.
• Optional air probe accessory for calculation of PMV/PPD thermal comfort indices.
