Heat Stress Monitor [QT-34]
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.
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.
Features
- 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.
