One-of-a-kind Clamp-on DC Ammeters
The Swain Meter™ Company manufactures portable clamp on DC ammeters that precisely measure the magnitude and direction of DC current flow on any conductor. Used both onshore and offshore, Swain DC clamp on amp meters accurately read current from 5mA to 200 Amps with a resolution of 1mA in the 0-2Amp range.
Swain MER™ and Auto MER™ 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.
Two models of Swain are manufactured: the Auto MER™ and soon to be released Auto MER™ GEN 3.0 meters. Both offer fast, precision accuracy to read magnitude and direction of current. The Auto MER™ GEN 3.0 meter will be capable of AC and DC amperage measurements. This new meter will also have built in measurement data storage capable of being downloaded via USB. A rechargeable battery has been incorporated into the Auto MER™ GEN 3.0 meter as well.
The MER™ meter has been discontinued as of January of 2018.
Auto MER™ Meter
The Swain Auto MER™ DC Current Clamp Meter is a test meter for corrosion detection that features auto ranging and auto zeroing. MER™ stands for Magnetic Error Reduction.
Our Pelican brand case design is water resistant and uses dust proof, military style, Cannon Connectors. Data logging output jacks are a standard item on all Auto MER™ and MER™ Meters.
