Power Quality, Insulation and Ground Resistance Testers Cut costs and stay safe. Improving energy efficiency, reducing downtime, and prolonging the life of your equipment are some of the ways you can save money with Amprobe tools. Personal computers, photocopiers and fluorescent lighting are all putting greater power demands on facilities. When power becomes distorted or “dirty”, it can very quickly destroy mission critical equipment. Ensuring you have clean energy to support your equipment and avoid costly downtime has become increasingly important

Cut energy costs and improve operating efficiency with Amprobes full-featured DM-III Multitest F, a three-phase power quality recorder that provides the essential functions and capabilities required to operate accurately and effectively in today’s demanding electrical environments. The DM-III Multitest F measures and records a broad spectrum of power quality parameters with True-rms accuracy and is compatible with a wide range of current transducers.  This full-blown power quality recorder also measures ground resistance, tests insulation of wires, cables transformers and electrical motors.
