MER2® DC Amp Clips and Clamps are “Swain Sensors” which precisely detect the magnitude and direction of direct current flowing on magnetized conductors during normal operation without interrupting the circuit. Swain portable DC amp clips for cathodic protection above ground and subsea are manufactured from 2″ to 10″ in diameter.
MER2® (Magnetic Error Reduction doubled) type DC Amp Clips are generally more accurate for measuring direct current with a non-contact sensor.
- Constructed to reduce errors due to non-uniform magnetic fields common on steel pipe, near rebar, or near the battery in cars and trucks.
- Protected from 300 A overload.
