Alpha-Log Data logger

Alpha-Log Data logger


Alpha-Log is the latest model of the LSI LASTEM’s data loggers' family. It contains the most efficient technical solutions coming from 40 years’ experience of LSI LASTEM about data acquisition systems. Alpha-Log was created with the clear need to be an autonomous acquisition system, but also with capability to be integrated into more complex systems. Special care has been given to the system usability and data management features, realized having in mind the most state of the art requirements. Based on a Linux architecture, it contains the power of this kind of operating system, but also an optimized hardware with extreme low consumption. Also, the usability and data management as well as the data output part has been designed having in mind the most modern needs.
