Feature:
Measures various kinds of materials from minute magnetic cores to permanent magnets.
The complete interactive software does not need trained skills.
The drift adjustment of the integrator is fully automatic.
The measuring speed is constant.
The latest digital feedback function added to the existing analogue feedback circuit makes it possible to measure test materials with the characteristics of radical rise of B accurately and easily.
All the measuring units are adopted SI unit.BH-5501 record DC magnetizating characteristics which is the basic characteristic of magnetic materials with high precision in a short period of time. And the data of various characteristics are computer-processed.
Our long years of experience developed the new model with high precision and easy operation.
Except for putting in and out the test materials, all operations and settings are made interactively through computer key-boards so that anyone can measure easily.
