SML-BH01 Hysteresisgraph Loop Tracer

The SML-BH01 automatic hysteresisgraph/hysteresis loop tracer is a computer system used for measuring the magnetic properties of soft magnetic materials at frequencies ranging from DC to 1KHz following ASTM standard test procedures.

Soft magnetic materials/soft magnetic composites are characterized by high magnetic induction, high magnetic permeability, low coercivity, and low loss.  The key to accurately determine these parameters is to ensure measured sample forms magnetic close circuit (no end magnetic poles).   One example is to make a sample in a ring shape wounded with primary and secondary coils for generating field and detecting magnetic flux.
