Heat Stress Monitor

Heat Stress Monitors:

The item to be purchases is similar to the TSI QT-34 Heat Stress Monitor, Datalogging, Part #QT-34
1. Wet Bulb Globe Temperature (WBGT) Heat Stress Monitor (Quantity - 31)
The meters sought will measure the environmental conditions needed to accurately calculate, display and record the Wet bulb Globe
Temperature (WBGT). The WBGT must be derived using the following equations.
- Outdoor: WBGT=0.1 x (Dry Bulb) + 0.7 x (Natural Wet Bulb) + 0.2 (Globe Temperature)
- Indoor: 0.7 x (Natural Wet Bulb) + 0.3 (Globe Temperature)
- The dry bulb temperature is the ambient air temperature. This is the temperature without impacts from other factors
- The natural wet-bulb temperature is the lowest temperature that the air may be cooled through the process of evaporation
only (given a constant pressure). For the purposes of this contract the devices sought shall measure the natural wet bulb by
thermometers that are wrapped in wetted wicks.
- The Globe Temperature (GT) measures solar radiation and other sources
-The devices shall be portable and data logging.
Quantity: 31
