55820 Hysteresis Loop Tracer has been designed specifically to have a precise knowledge of various parameters of ferromagnetic substances and the ability to determine them accurately are important aspects of magnetic studies.

These not only have academic significance but are also indispensable for users of magnetic materials. This unit is self contained and does not require any other equipment except CRO. Practical experience on this set up carries great educative value for Science and Engineering Students.
