Login Digital Epstein Tester Model
Model EP400
Digital Epstein Tester EP-400 is designed to measure AC magnetic properties of flat rolled magnetic materials at high frequency by using Watt-meter, Ammeter, Voltmeter and Source. Epstein bridge test method is a fundamental method for evaluating the magnetic performance of flat-rolled magnetic materials in either sheared or stress relief annealed condition. This test method is suitable for design, specification acceptance, service evaluation, and research and development.

Epstein Tester
S21 and S21R Series
Incoming material inspection can be very useful where strict quality standards are maintained. It saves a lot of processing cost since lossy material is inspected at the entry level before it goes to production level. Epstein Stack testing is one of the oldest and widely used methods for electrical sheet testing.
