The Amprobe ACF-3000DM-A current transducer measures and reduces electrical current in high-voltage wires and cables for safe testing. It is used with an DM-II Plus or DM-II PRO Power Quality Recorder (sold separately). The unit measures current from 0 to 3,000A. The flexible extension wire jaws open far enough to perform tests on conductors up to 7” in diameter.

Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.
