PQ3470-12 1200A 3-Phase Graphical Power Analyzer/Datalogger Kit by Extech
The PQ3470 is a 3-phase graphical power and harmonics analyzer/data logger capable of logging up to 30,000 sets of measurements on a removable SD memory card. The meter features a 3-phase voltage or current unbalanced ratio (VUR, AUR) and unbalanced factor, captures transient events (including dip, swell, and outage) with programmable threshold (%), a wide sampling rate range (2 seconds to 2 hours), a built in clock/calendar. Complete with 4 voltage leads with alligator clips, 8 AA batteries, SD card, 100-240V AC adaptor, three 1200A current probes and case.
Features
- Large dot-matrix, sun-readable, graphical, backlit LCD
- Full system analysis with up to 35 parameters: V (phase-to-phase), V (phase-to-ground); A (phase-to-ground); KW / KVA / KVAR / PF (phase); KW / KVA / KVAR / PF (system); KWH / KVAH / KVARH / PFH (system); Phase angle
- Select 200A, 1200A Current Clamps or 3000A Flexible Current Probes (sold separately)
