The PQ3350 is a comprehensive analysis and datalogging tool designed for use on single, 3-phase, 3-wire and 4-wire systems in order to carry out extensive evaluation of power quality. Featuring a large size LCD screen with backlight for use in darkened conditions, this tester can display up to 35 parameters simultaneously on screen, providing a full view of power quality during one test.

Since this power quality tool is also a datalogger, it includes the ability to store up to 54428 single phase readings or 17476 3 phase readings directly on the devices' built-in memory. Via a USB connection it is possible to download this information to PC for further analysis using Extech's included software package.
