Purkeys' Milliamp Clip-On Ammeter is designed to detect parasitic loads by accurately measuring low current in electrical systems without disconnecting cords from the power source.

The ammeter precisely measures the magnetic field generated by current flowing through the conductor by clamping its interlocking jaws around a wire.

The clip-on ammeter allows for accurate and quick diagnosis of electrical systems and is able to accurately measure low current down to a milliamp. By finding parasitic loads, a technician can address the issue and reduce battery depletion and damage.
