Megger MJ15 - Insulation Resistance Tester - 5kV


The Megger MJ15 is a compact 5kV insulation tester. It is very simple to use and provides a quick and accurate reading of insulation resistance. The instrument uses an analog display with a maximum reading of 20 GΩ and has an additional hand-cranked generator.

The instrument operation is extremely simple with a choice of push buttons. A locking button simplifies long term testing or a non-locking version is preferred for maximum safety. A voltage range enables measurement of AC or DC conductor potential with four test voltage available at 500V, 1kV, 2.5kV and 5kV.

A bezel allows a scale plate overlay to be added with pass/fail bands for go/no-go testing. This is particularly useful for less experienced users and enables a rapid decision to be made. The MJ15 is built into a rugged case design for outdoor use and is supplied with a soft carrying case, a test lead set, test record cards and batteries.
