Description
Worldwide Quality and Reliability
Swain Meters are field-portable, non-contact ammeters for corrosion protection, fault location, and quality assurance. They are accurate, convenient, and trouble-free under normal field conditions, even for underwater measurements. A Swain Meter is calibrated and sold as a set with a Swain DC Amp Clip™ or DC Amp Clamp™.

Swain Meter FAQ |
What are Swain Meters? | |
Swain Meters are precision built and calibrated portable meters, coupled with clips or clamps, used to measure current magnitude and direction on conductors in the atmosphere, underground, or under water. They as suitable for AC or DC. They are ideal for pipe, pipelines, cables, supports, rebar and other structures where corrosion may be a problem. | |
What sets Swain Meters apart from other clamp-type meters? | |
All Swain Meters utilize Magnetic Error Reduction (MER) technology. This greatly reduces the effect of the Earth’s magnetic field, which introduces errors into the measurements of all other clamp-type meters. | |
What is the differences between clips and clamps? | |
Clips are single-piece, spring loaded sensors, which can be installed and removed by compressing a handle. Clips range in size from 3/4” to 6” diameter. Clamps are larger sensors. They are manufactured as matching half-circles, which are and bolted together around the conductor to perform measurements. Clamps range in size from 6” to 60” diameter. Custom sizes can be produced on demand. | |
What is the difference between MER and MER2 sensors? | |
MER stands for Magnetic Error Reduction, which minimizes magnetic interference problems. MER is the older and less expensive sensor (clip and clamp) technology. MER2 is a newer, patented sensor technology, which reduces magnetic interference by a factor of 2 or 3 and cuts zero errors in half compared to MER. | |
What precision can a Swain Meter achieve? | |
Swain Meters are capable of a 1 milliampere (mA) resolution on 3/4” to 13” clips and clamps, 1 to 10 mA on 14” to 24” clamps, and 1 to 100 mA resolution on 15” to 60” clamps. |
