Product Overview

The 212159 CAL from Megger is a MJ series major Megger insulation resistance tester. Quality is crafted into every major MEGGER insulation tester with excellent test voltage regulation, direct measurement readout and an external guard terminal to eliminate surface leakage current from the measurement. It is portable, self-contained instrument designed to give rapid and accurate measurements. Power for model is derived from a low-voltage, hand cranked generator which has been designed to be easy to turn even under full load conditions. This tester has been designed for convenience and ease-of-use when testing complex or larger electrical installations and commissioning, servicing or maintaining electrical equipment and also for the safe testing of motors, generators, cables, switchgear, transformers, distribution networks, industrial and domestic installations, components and appliances.
