LSI LASTEM Heat Shield Portable Wireless WBGT Meter

  Quick, reliable and accurate assessment of indoor and outdoor WBGT index.
  Additional Heat Index, Humidex index calculation.
  Support for ISO7730 thermal comfort analysis with PMV-PPD indexes, heat and cold stress Predicted Heat Strain (PHS), Insulation Required (IREQ).
  Built-in radio technology for simultaneous, wireless monitoring in different locations/heights.
  Rated IP54 to withstand harsh environmental conditions even outdoor.

LSI LASTEM's Heat Shield Portable Wireless WBGT Meter includes the global temperature, dry bulb temperature, relative humidity, wet bulb temperature and also displays online WBGT outdoor & indoor index, humidex and heat index.

The LSI LASTEM Heat Shield's incorporated radio technology allows it to support up to 2 satellite units to calculate the different levels of WBGT or in different locations. When it is equipped with an anemometer, this unit may be used for the very accurate analysis of thermal environments by means of the well advanced software that is accessible on the market for this specific requirement, GIDAS TEA.

The Heat Shield Portable Wireless WBGT Meter is stable once it is placed on any surface that is horizontal, although it can be mounted or hand able on a standard photographic tripod. No configuration is needed by the PC. With the philosophy of on-and-play, the measurement may be displayed in a few seconds from the power on. HS Manager is the software that comes along with each Heat Shield unit in the LSI LASTEM range.

Rechargeable batteries ensure measurements can be taken for up to 400 hrs. The Heat Shield is very robust and compact and it is proposed to withstand any harsh environments too. IP54 guarantees protection in outdoors or in humid or dusty conditions.
