Amprobe DM-III Multitest & DM-III Multitest F Three Phase Power Quality Analyzer / Recorders

Amprobe's DM-III Multitest full-featured Three Phase Power Quality Recorders provide the essential functions and capabilities to maintain, diagnose and troubleshoot electrical systems.Amprobe's DM-III Multitest full-featured Three Phase Power Quality Recorders provide the essential functions and capabilities to maintain, diagnose and troubleshoot electrical systems.

These easy to use instruments are 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), frequency and phase sequence.

The DM-III Multitest F is a multitalented device that provides everything an electrical engineer or a technician needs to perform maintenance or installations on the electrical system.

The DM-III Multitest measures and records three phase: voltage, current, voltage anomalies (sags or surges), harmonics, energy and power (active, reactive and apparent), power factor (true and displacement), frequency and phase sequence.

It can test wires and motors for proper insulation, as well as measure the resistance of the grounding systems and resistivity of the soil. On board memory makes it a perfect tool for preventive maintenance applications.
