Swain Models
High Quality digital DC Ammeters capable of measuring 5mA through 200Amps.
Two models of Swain are manufactured: the MER and AutoMER. Both offer fast, precision accuracy to read magnitude and direction of current.
MER Meter® (Magnetic Error Reduction) reduces magnetic interference from current measurement. A MER meter offers manual zeroing and ranging.
AutoMER™ model combines automatic control with Magnetic Error Reduction -- range and zero are set automatically.
MER2™ Sensors (Clips and Clamps) are available from 3/4" to over 100" diameter aperture. MER2 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.
Applications Off-shore anodes & flexible pipe current can be measured at 1000 ft. depth or more. Both clips and clamps may be mounted on a ROV. Clamps can be permanently buried underwater or even underground.
Impressed Anode Current is measured by clipping around the cable. There is no need to open the cable or add shunts which increase resistance.
