Power Clamp Meters - Extech PQ3470
PQ3470: 3-Phase Graphical Power & Harmonics Analyzer/Datalogger
Datalogging Power Analyzer (up to 30,000 sets of measurements)
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 and case. Clamp probes sold separately.
