DC Ammeter Shunts

Custom shunts are available in any Amperage and Millivolt rating.   We are able to certify any make of shunt to an uncertainty of ± 0.1% traceable to N.R.C., N.I S.T., S.I.   Our LA, LB and LC shunts are built to U.S. Military Specification A-A-55524 which supersedes MIL-S-61B.   We can supply Calibrated Leads (0.065 Ohms), 5 feet long, for connecting shunts to analog panel meters.
