DM-II Plus
Power Quality Recorder
Amprobe’s DM-II PLUS is a full-featured three phase
power quality recorder to maintain, diagnose and
troubleshoot electrical systems. It measures and records
a broad spectrum of power quality parameters. Easy
to use, it’s capable of measuring and recording voltage,
current, voltage anomalies (sags or surges), harmonics, energy and power (active, reactive and apparent),
power factor (true and displacement), and frequency.
This unique product comes as a complete kit with current
transducers and an increased memory size for data
storage, larger display size, and real-time downloading
using Amprobe’s unique Download Suite software.
