Cut unscheduled downtime and reduce shock hazards with the Amprobe AMB Quickly check the insulation resistance value of electric equipment and lines with this small, easy to operate tester.

This tools lets us know if a wire has been nicked or damaged and will leak voltage once energized. Saves us some headaches with dim lights.

This little device can save lives to.


Amprobe Amb-3 Insulation Resistance Tester Meter Megger 500 Volts
