Meteo-42 is easy to configure – from your office or directly on site – using the same communication tools and software as the Meteo-40 plus: AmmonitConnect and AmmonitOR cloud. Our data loggers are easy to install and work reliably worldwide.
Meteo-42 brings those technical innovations:
•    Three RS-485 ports
•    Faster processors
•    Better grounding for more accurate measurement of analog quantities
•    More flexible switches.

Meteo-42 will be available from August 2023 at the same price as Meteo-40 plus.
