The data logger for meteorological monitoring
E-log has been explicitly designed for environmental applications: it is equipped with specific inputs for a wide range of sensors and calculations of derived quantities. E-Log stores the data from the connected sensors and supports different communcation protocols both in input and output. Robust and reliable, E-Log makes measurements possible even in the most severe environments, while the 16-bit A/D converter ensures accurate and reliable data in classic meteorological, hydrological and air quality applications and – more generally – in any environmental application.
