Electricity Meters
Landis+Gyr E850
Precise values for all billing applications, comprehensive data for network operation: from the very start, the ZxQ series from Landis+Gyr was developed with grid applications in mind. With its exceptionally fast measurement system, high data resolution and proven operational security, it is clear that the ZxQ was designed for use in all applications. Lire la suite…
