QUESTemp 48N Heat Stress Meter
The QUESTemp 48N model was specifically engineered for the Department of Defense Ashore and Afloat Operations in which conditions require hand’s free monitoring, in-the-field user RH/WBGT sensor alignments, and snapshot measurement logging (called “event logging mode”).
The QT48N measures and calculates the dry bulb, wet bulb, globe, WBGT outdoors,and relative humidity with two different types of data logging modes – as a time history session or an event logging mode.
You also have the capability to measure stay times in order to manage work/rest regimens. Guidance is based on the screening criteria for heat stress as defined in the ACGIH TLV Handbook, U.S. Navy PHEL charts, and Flag Conditions for U.S. Navy/Marine Corp. Ashore.
Features:
- Waterless Web Bulb
- Engineered for DoD Ashore and Afloat Operations
Includes:
- (Alkaline Battery)- Standard Accessories, (1)* Sensor Bar Assembly with Calculated Wet Bulb using Replaceable RH Sensor, and 2" Style Globe Sensor
*Sensor Bar Assembly (1) includes: 1 sensor bar containing a Wet Bulb, Dry Bulb, Globe Temperature & Humidity (%RH) sensors.
