Common mode inductor balance tester is also called filter balance tester. It is suitable for all kinds of common mode inductors, filter common mode inductors Ls, DCR balance measurement. Its measuring accuracy is up to 0.1% and it can meet the measurement requirements of production line quality assurance, incoming inspection and component design and evaluation. Equipped with a more comprehensive communication and control interface, the connection of automation equipment is simple and convenient.
