The Model PQL 120 (1MB memory) is a single-phase Power Quality Logger designed to measure and log from a complete suite of electrical and power quality parameters. It is accompanied by an easy-to-use report compliant software package.

The Model PQL 120 is designed for North American commercial, industrial and residential applications, and is plugged into a standard AC receptacle. In turn, any 120V load, may be plugged into the Power Quality Logger: office equipment, data equipment, machinery, compressors, heaters, motors, etc.

The Model PQL 120 measures, records and stores selected parameters in its 1 MB memory. Along with the standard electrical parameters (V, A, W, Var, PF...), it also stores the Power Quality of the input waveforms (Harmonics, THD, Surge, Sag, K-Factor...). The recorded information is retrieved from a computer via an RS-232 serial link using the report compliant DataView® software package, which provides graphs, data and pre-configured reports.
