One-of-a-kind Clamp-on Ammeters
The Swain Meter™ Company manufactures portable clamp on ammeters that precisely measure the magnitude and direction of DC current flow on any conductor. Used both onshore and offshore, Swain instruments accurately read current from 5mA to 200 Amps with a resolution of 1mA in the 0-2Amp range.
Swain MER® and AutoMER™ 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.
Swain clips and clamps (MER2™ Sensors) are constructed to reduce zero offset error and manufactured with aperture diameters from ¾" to 82" to date.
Our technicians build each meter and sensor by hand and calibrate them to exact specifications.
Swain Meter field portable, custom built, clamp-on DC Ammeters:
- Sizes range from 3/4” through 100”diameter
- Clips and Clamps are non-contact devices
- Measure DC current from 5mA to 200Amps
- One mA Resolution in 2A range
- Cancels AC interference for accurate reads
- Shows direction and Magnitude of current
