The ZES ZIMMER LMG670 is the first Power Analyser without compromises. Its DualPath architectures offers simultaneous narrow- and broad band measurements through two independent measurements paths.

The LMG can be configured with up to 7 measurement channels (or 6 including an IO card for control & monitoring process signals). Three different Channel Measurement Modules are available: A1 module for high precision broadband measurement, B1 module for general purpose measurements and the C1 module for precision 50/60 Hz measurements.
