This version of Extech's PQ3350 comes as standard with a selection of 3000A 24" flexible current clamp probes. Another version - the PQ3350-1 - comes with 1200A 12" flexible current clamp probes.
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.
Tests that this device can perform are AC voltage up to 600V, AC current (via clamps) to 3000A, active power, apparent power and reactive power, power factor, frequency, phase, harmonics, crest factor, active power energy and reactive power energy.
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.
