The design and manufacture of TYU-2000D DC Hysteresisgraph by Hunan Loudi Tianyu Electronic Co.,LTD completely meets the national standards GB3657-83 and the measurement verification standard JJG354-84、JJG407-86 and relevant IEC standard.
This kind of equipment has a big advantage that not only can obtain magnetic hysteresis loop and the parameter over the magnetic hysteresis loop by scanning the magnetic field but also can measure the characteristic of the quasi-static magnet in impact method. It made the magnetic measurement thoroughly get rid of dependent on ballistic galvanometer, so that it can avoid the non instantaneous error made by using ballistic galvanometer and it can save and develop the method of impulse measurement. The operation is very simple and the sensitivity can up to 4×10-8Wb, which already over the best of ballistic galvanometer.
