Heat Shield meter displays on-line WBGT indoor& outdoor index plus Heat Index and Humidex indexes. Furthermore, if ESV125 anemometer is connected, Heat Shield can calculate directly the PMV-PPD comfort index (ISO7730). Thanks to its built-in radio technology, Heat Shield can support up to two satellite units to assess analysis at different levels or in diffe-rent locations. It is possible to download the stored data using HS Manager PC program included with Heat Shield. From HS Manager it is also possible to export the data to GIDAS TEA program, used for further thermal environments analysis as Predicted Heat Strain (PHS), Insulation Required (IREQ), Duration Limit of the exposition (Dlim). GIDAS-TEA program will also allow in-depth analysis of WBGT, PMV and PPD indexes (read Gidas-TEA catalogue MW9006-ENG-06)

Heat Shield is equipped with built-in sensors to measure:
- globe temperature (tg)
- wet bulb temperature (tnw)
- dry bulb temperature (ta)
- relative humidity (rh)
- air speed (va).
Heat Shield calculates on-lie and display the following indexes:
- WBGT indoor and outdoor index (ISO7243). Up to 3 locations simultaneously when satellite units are used
- Head - Torso-Ankle weighted average WBGT (ISO7243)
- Heat index according to 1990 National Service (NWS) Technical Attachment (SR 90-23)
- Humidex according to J.M. Masterton and F.A. Richardson of Canada's Atmospheric Environment Service equation (1979)
- PMV-PPD (ISO7730) comfort index when anemometer sensoris connected. Metabolism (met), Cloth (Clo) and Mechanical ratio (ETA) values are required for the subject under evaluation.
