Portable wireless WBGT meter – Heat Shield

Compact solution for measuring the main comfort and thermal stress indices


Compact solution for measuring the main comfort and thermal stress indices

Heat Shield meter displays on-line WBGT index (without or with solar load), WBGT Eff and Delta to the WBGT Ref, plus Heat Index and Humidex indices. Furthermore, if ESV125A anemometer is connected, Heat Shield can calculate directly the PMV-PPD comfort index (ISO7730). The models with built-in radio technology can support up to two satellite units to assess analysis at different levels or in different 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 (Dim). GIDAS-TEA program will also allow post-processing analysis of WBGT, PMV and PPD indexes (read Gidas-TEA catalogue MW9006-ENG-06).



  • Quick, real-time, reliable and accurate assessment of heat stress WBGT index with or withour solar load (ISO7243);
  • Real time assessment of the WBGT Eff and WBGT Ref with Delta to
    the limit calculation for immediate verification of the distance to
    the limit (ISO7243 2017-08 edition);
  • Real-time assessment of the thermal comfort PMV- PPD index (ISO7730);
  • Verification probe for assessment of the system calibration;
  • Stand alone modules (ELR600M / ELR605M) and built-in radio technology models (ELR610M / ELR615M) for simultaneous, wireless monitoring in different locations/heights;
  • Rated IP54 to withstand harsh environmental conditions;
  • Use of the measured wet bulb temperature for the calculation of the WBGT;
  • 8 MB memory for extended data logging;
  • Battery Life: 200h (with radio on 20h);
  • Automatic start/stop of measurements;
  • Design and performances according to ISO7243 and ISO7726;
  • HS Manager program included for data downloading, data assesment and data reporting;
  • Data export to TEA software for additional features, including additional index calculation as: Predicted Heat Strain (PHS-ISO7923), Required Clo-thing Insulation (IREQ-ISO11079) index.
  • ESV125A hot wire anemometer for microclimate (moderate) assessment
