Use Extech's PQ3350-1 to accurately carry out power measurements, analysis and datalogging of single, 3-phase, 3-wire and 4 wire systems.

Once connected up to a system the PQ3350-1 has an extensive suite of measurement functions which can be displayed as harmonic analysis, power analysis or phase analysis. The tester can be used to measure AC voltage levels, AC current, active power (kW), apparent power (kVa), reactive power (kVAR), power factor, frequency, phase, harmonics, crest factor, active power energy and reactive power energy (the included flexible current clamps are used for current measurements).

The PQ3350-1 includes a large amount of functions designed for specific measurements including simultaneous display of harmonics and waveform, display of waveform with peak values (1024 samples/period), analysis of total harmonic distortion and much more.

In order to make sure that results are stored for later use the PQ3350-1 includes built-in datalogging functions allowing it to store up to 52428 records for single phase or 17476 records when used on 3 phase systems. This information can be downloaded directly to PC via a USB connection and interacted with using the included software package.

This tester is available in two variations: this version, the PQ550-1, comes with 1200A 12" flexible current clamp probes. The other model, the PQ3350-3, comes with 3000A 24" flexible current clamp probes. The basic functionality of both testers is the same.
