The CMM72 energy quality analyzer measures all the electrical parameters of the Low and Medium voltage installation. It represents the state of the art in electrical measurement. Its advanced power quality analysis and metering features can be used for all types of energy management and electrical installation monitoring applications. The device features a large high-resolution color LCD screen.

Thanks to its capacitive touch keys, it offers an IP64 front panel protection rating of the cabinet, allowing it to be installed in the most severe operating conditions (mining industries, food industries, etc.).

The instrument has two slots for inserting extension modules, which allow for expanding the instrument’s functionalities.
