About Swain Meter
Portable DC Current Clamp Ammeters
The Swain Meter Company manufactures portable DC current clamp meters that precisely measure the magnitude and direction of DC current flow on any conductor. Used both onshore and offshore, Swain instruments assist with corrosion monitoring and cathodic protection by accurately reading current from 5mA to 200 Amps with a resolution of 1mA in the 0-2Amp range.

Clamp On DC Meter
Swain MER® and AutoMER corrosion monitoring meters cancel out AC interference up to 10Amps to establish a +/- 1% reliability specification. MER is "Magnetic Error Reduction", a patented technology (US patent 6,323,635 1) is constructed to cancel out the earth's magnetic field and establish an error-free baseline from which precise readings are obtained.

MER2 Corrosion Sensors are used to measure actual pipe current, both magnitude and direction of flow, more accurately and in less time, above ground, under water and permanently buried. These Clips and Clamps are available from 3/4" to over 100" diameter aperture. More...
How to Use Our Products
DC current clamp ammeters are tools for corrosion monitoring and solving cathodic protection problems. They can measure interference in a gas pipe or support column, measure anode current on a subsea structure, or find lost cathodic protection current due to bad pipeline insulation, defective anode leads, or poor structural electrical contact.
