The QUESTemp™ 34 is a rugged, easy to use, data logging thermal environment monitor. It combines WBGT index values with relative humidity measurements to calculate the heat index.
 
Kit includes QUESTemp™ 34 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.
Humidex/heat index reading.
Data logging.
Intrinsic safety certification.
 
This data logging heat stress monitor offers the user the ability to output data directly to a serial printer or download to Detection Management Software (DMS) for storage, retrieval, analysis, reporting and charting of the heat stress monitoring data. 
 
The QUESTemp° 34 QT-34 (with Alkaline Battery) includes Standard, (1) Sensor Bar Assembly, and 2" Style Globe Sensor.
