A new generation of magnetic measurement apparatus was developed in 1986 by National Institute of Metrology P.R.China and Electric Research Institute of Loudi Region cooperatively. The first set of MATS-2000 Auto Test System of Magnetic Materials of China was developed in 1989 in Loudi Region, which passed certification of China Association for Science and Technology in 1990. The measurement precision of the product reaches or exceeds the regulations of international IEC standard and national standards and filled the blank of magnetic measurement field in our country. The product, leading an advanced level in the world, is recommended as national-level new product 90'' of magnetic measurement apparatuses. The product was awarded the first class award of technology advancement by China State Bureau of Technical Supervision in 1990 and was awarded the second class award of national technology advancement. Through undertaking 7th National Magnetic Academy Meeting in november 1991, it established the leading position for Loudi in the national science research and development and made MATSTM become a pronoun of magnetic material measurement apparatus and promote the domestic production of magnetic measurement apparatus.

Founded in 2000, Linkjoin Technology Co., Ltd. of Hunan Province is a high-tech share enterprise initiated by the engineers of original Electronics Technology Institute of Loudi Region in joint funds and engages in the development and manufacturing of magnetic material automatic measurement devices. Depending on tens of years'' development experience of several engineers in the subordinate Electro-Magnet Institute, the company has purchased completed set of overseas measuring apparatuses and equipments in progression and continuously developed measurement apparatuses covering permanent magnetism (rare earth), soft magnetism and silicon steel. The products developed by the company have been leading the advanced level of the magnetic measurement industry all the time. By now, through the modern management and sale models, Linkjoin Technology Co., Ltd. has become the largest and the most comprehensive domestic manufacturer and supplier of magnetic material measurement equipments in our country.

As the high content of technology, convenient application, completed functions and very competitive price, the products have gained high appraisement from the consumers and market return. At present, it has already exceeded 10 millions Yuan in raw material of magnetic material, components, electro acoustic, motor and transformer industries as well as Linkjoin brand magnetic measurement apparatus operated by the scientific research institute. Part of the products are adopted by American companies, Taiwan companies, Japanese companies and Hongkong companies, which makes the company the most competitive and creative enterprises among the same industries.
