Megger Insulation Tester

The Megger 5kV compact insulation tester provides an accurate and quick reading of insulation resistance. This tester is easy to use and has an analogue display with a maximum reading of 20Gohm. It comes with a hand-cranked generator plus batteries. If the test button is pressed the tester uses battery power. Otherwise, the crank handle is turned to save battery power or for use when the batteries are unavailable.
