Description
Overview
GAOTek Three Power Quality Analyzer with built-in data storage is specially designed high precision testing instruments which can be used to test power grid waveform distortion, voltage fluctuation and flicker, harmonic content and unbalanced three-phase power quality problems. At the same time it also has the functions of electric parameter test, the vector analysis. This power quality analyzer comes with USB interface, which makes it easy to copy the data directly from the backstage management computer. It also has powerful data management software and the real-time sampling data can be directly uploaded to the background management computer, it will be a more comprehensive and more rapid processing in the background.
