• Extech PQ3350-3  3-Phase Power & Harmonics Analyzers

Complete with 3000A 24" flexible current clamp probes:

Complete with 3000A 18" flexible current clamp probes. Datalogging of single and 3-phase/3-wire or 3-phase/4-wire systems (up to 52,428 single phase readings or 17,476 3-phase readings). Flexible clamp probes can be used for wrapping around bus bars and wire bundles. Large backlighting LCD displays up to 35 parameters in one screen. Clamp-on True RMS power measurements with on-screen Harmonics display. Simultaneous display of Harmonics and Waveform. Display of Waveform with Peak Values (1024 samples/period). Analysis of Total Harmonic Distortion (THD-F). Maximum Demand (MDkW, MW, kVA, MVA) with programmable period. Adjustable CT ratio (1 to 600) and VT ratio (1 to 3000). Graphic Phase diagram with 3-Phase system parameters. 3-phase Voltage or Current Unbalanced Ratio (VUR, VIR) and Unbalanced Factor (d0%, d2%). Calculated Unbalanced Current through Neutral Line (In). Capture 28 Transient events (including Dip, Swell and Outage) with programmable threshold (%). Optically isolated USB interface with software to download Waveforms, Power Parameters and Harmonics. Includes 3 flexible current clamps, 4 voltage leads with alligator clips and retractable plunger clips, 8 AA batteries, universal AC adaptor, software, USB interface cable, and case.
