The William H. Swain Company, under ownership of Mr. William H. Swain, was world renowned as a manufacturer of precision instrumentation used to measure Direct Current (DC) on a variety of structures including pipelines, current and non-current carrying cables, power line tower legs, and any other conductor capable of carrying current.

Products such as the MER™ (Magnetic Error Reduction) Meter, MER™Sensor, MER2™ Sensor, and AutoMER™ serve as the industry leader in precision measurement.  Produced in combination with custom crafted clips and clamps to fit conductor sizes ranging from 3/4" to over 82", the William H. Swain Company has defined quality and set the standard for reduced-error measurement.

Swain Meters work well under adverse environments and have proven to be unique and reliable for accurate data. They are used globally and exported worldwide. We are currently seeking resellers outside of the United States.

The Swain Meter™ Company is honored to carry the standard established by The William H. Swain Company.
