Permanent Magnetism Material Auto-testing Equipment
TYU-2000H style Permanent Magnetism Material Auto-testing Equipment of Hunan Loudi Tianyu Electronic Co.,LTD was released after many years of elaborative design by our scientific research personnel, which is made on the basis of MATS-2000 style Permanent Magnetism Material Auto-testing Equipment(Original style) according to the development of the software and hardware technology.
It can suitable for the testing of ordinary Permanent Magnetism Material (Such as Al Ni & Co, ferrite and making bonded magnet) and it also suitable for testing strong-magnetic-field Permanent Magnetism Material (eg Nd-Fe-B). All the measure process can be finished automatically except sample placement. Compared with the traditional method, the testing of TYU-2000H style Permanent Magnetism Material Auto-testing Equipment is more reasonable, quicker, effective and good digital repeatability because the application of the computer's technique is maximally adopted, for example, the automatic modification of integrator zero point drifting, the modification of hall nonlinearity, the technology of special excitation waveform design and the technology of software digital filter.
The popular graphical interface is adopted by the testing software of this equipment, so it can run under the WindowsXP/2000/98 operating system. This kind of interface is very simple and easy to learn and operate. The testing software is green software, with no installation, no operation to the system registration form. It can run directly.
