LSI LASTEM is an Italian company who specialises in the design and manufacture of high specification environmental monitoring systems.

Instruments that LSI LASTEM have designed are suitable for almost every type of application imaginable. They offer precise and trustworthy measurement of all sorts of environmental parameters. LSI LASTEM equipment is suitable for both for temporary and long-term monitoring plus also for indoor and outdoor use.

As well as the sensors, LSI LASTEM has produced a comprehensive range of data loggers, software and accessories, so users have everything they need.

Two comparable products available are the 3M QT34 and 3M QT36. However, these products cannot perform measurements at three levels. No other products other than LSI LASTEM can perform measurement at three positions, as LSI LASTEM have a wireless solution.

LSI LASTEM comply with the following regulations:

  ISO7243 Estimation of the Heat stress on working man based on WBGT index
  ISO7730 PMV Predicted mean vote
  ISO7730 PPD Predicted % of dissatisfied
  ISO7730 DR Predicted % of dissatisfied by draught
