What are Swain Meters?

Swain Meters are precision built and calibrated instruments, coupled with clips or clamps, used to measure current magnitude and direction on conductors in the atmosphere, underground, and under water.

What sets Swain Meters apart from other amp clamps?

Swain Meters greatly reduce the earth’s magnetic field effect which introduces error into all other meters measurements.

What level of precision can a Swain Meter™ achieve?

Swain Meters are capable of a 1 milliampere (mA) resolution on ¾” to 13” clips and clamps, 1 to 10 mA on 14” to 24” clamps, and 1 to 100 mA resolution on 15” to 82” clamps.

What applications can Swain Meters be used for?

Swain Meters can be used to measure DC current in most conductors.  Applications include, but are not limited to: aboveground, underground and underwater pipelines, cables, supports, rebar.

What is the difference between clips and clamps?

Clips are installed and removed by hand depressing a jumper cable type handle.  Clips range in size from ¾” to 6”. 

Clamps are manufactured in matching half-circles and bolted together around the conductor during measurement.  Clamps range in size from 6” to 82”.  Custom sizes can be produced if needed.

Where are Swain products manufactured?
