Meteo-40 is available in three configurations - for every application the best suitable data logger. Meteo-40 is designed for high performance and accuracy working at a minimum of power. You can reliably supply a complete measurement system with only a 50 W solar module - even in remote sites under extreme weather conditions.

We design each measurement system according to your requirements including all meteorological sensors, communication and power supply system. Storage in a CE-certified steel cabinet protects the data logger against weather and condensation damage as well as theft and vandalism.
