The EG4130 Pro combines an energy meter, data logger, and a web server. This powerful combination lets you measure, store and retrieve (V, A, VAr, kWh, etc.) data directly from the device or from a remote location via the internet. You can view historical and live data for the lifetime of the hardware with the unit’s convenient user interface (UI). Users have access to real-time values, long-term reports, an interactive graphical interface, and many other tools.
