Heat Shield includes globe temperature, wet bulb temperature the, dry bulb temperature and relative humidity and displays on-line WBGT indoor& outdoor index, Heat Index and Humidex. Thanks to its built-in radio technology, Heat Shield can support up to two satellite units to calculate WBGT at different levels (As per the recommendations outlined in ISO 7243: 1989) or in different locations. When equipped with the anemometer, the unit can be also used for accurate thermal environments analysis thanks to the most advanced software available on the market for this purpose, GlDAS TEA.

• Quick, reliable and accurate assessment of indoor and outdoor WBGT index
• Built-in radio technology for simultaneous, wireless monitoring in different locations/heights
• Rated IP54 to withstand harsh environmental conditions
• 8MB memory for extended data logging
• Battery Life: 400h (with radio on 20h)
• Automatic start/stop of measurements
• Probe design and performances according to ISO7726
• GlDAS TEA The most advanced software available on the market for Thermal Environment Analysis
• Support for ISO7730 thermal comfort analysis with PMV and PPD indexes, heat and cold stress Predicted Heat Strain (PHS), Insulation Required (IREQ)
