Established in 2002, Dandong Tongda Science & Technology Co., Ltd. is a national high-tech enterprise and ISO quality system certified company specializing in X-ray analysis instruments and X-ray non-destructive testing instruments, and has a number of invention patents and utility model patents.

In order to address the absence of a diffractometer in China, enterprises are committed to independent innovation, increasing investment in scientific research, strengthening collaboration with major universities and top domestic scientists, and continuously enhancing the technical level and upgrading products. The first X-ray single crystal diffractometer developed in China was officially launched in 2021, and has been widely applied in chemical, mineral, pharmaceutical and other material research fields. Both domestic and foreign users have praised its functionality and stability.

The company has expanded the factory area by over 1000 square meters, upgraded production equipment, actively managed material inventory, coordinated overall production arrangements, and made every effort to ensure the completion of all orders with high quality and quantity. In the company's workshop, a batch of assembled diffractometer is neatly arranged, and technicians are carefully debugging them before they are soon dispatched to the buyer.
