It is a high-tech enterprise supported by the Liaoning Provincial Government and the Dandong Municipal Government, and in 2013, 5 On the 15th, an academician expert workstation was established. The company is a professional manufacturer of X-ray analytical instruments and non-destructive testing instruments.


TD-3500 X-ray Diffraction Instrument

X-ray diffractometers are analytical instruments that study and characterize the composition and atomic structure of crystalline materials and materials. The TD-3500 X-ray diffractometer produced by Dandong Tongda Technology Co., Ltd. introduces the mature and stable programmable controller technology in industrial process control into the product design concept, making the TD-3500 X-ray powder diffractometer highly accurate and accurate. With good mechanical stability, durability, easy upgrade, easy operation and intelligent features, it can flexibly adapt to test analysis and research in various industries!

Vertical (θs-θd) goniometer 

TD series goniometer sampling imported high-precision bearing transmission, motion control is completed by a set of high-precision full-closed vector drive servo system, intelligent drive includes 32-bit RISC microprocessor, high-resolution magnetic encoder, can be minimal The motion position error is automatically corrected to ensure high precision and high accuracy of the measurement results. The angle reproducibility can reach 0.0002 degrees and the minimum step angle can reach 0.0001 degrees.

The TD-3500 X-ray diffractometer uses the θs-θd goniometer. The θs-θd goniometer refers to the horizontal placement of the sample, which is fixed, and the X-ray source (Source) and the detector (Detector) rotate at a ratio of 1:1. Goniometer. The development of this kind of structure goniometer can meet the requirements of special samples, such as liquid samples, sol-state samples, viscous samples, loose powder samples, bulk solid samples, in addition to the measurement of conventional samples.


Complying X-ray diffraction principle to qualitatively or quantitatively analyze polycrystalline materials such as powder samples and metal samples, and analyzing crystal structure. It is widely used in industrial, agricultural, defense, pharmaceutical, mineral, food safety, petroleum, education and scientific research fields.


• The instrument is plug and play

• Modular design and standardized interface technology solutions

• Advanced high frequency and high voltage power supply technology enables lower power consumption

• The highly integrated desktop cooling circulating water system TZL-30M makes equipment performance more reliable.

TDM-10 small X-ray diffractometer

TDM-10 X-ray small diffractometer is mainly used for phase analysis of powders, solids and similar paste materials. The device is small in size, light in weight, low in power consumption, and can quickly calibrate and test samples. The measurement accuracy of the position is 0.001°, which is used for computer control, and the data collection and timely processing can be directly seen under the Windows window.
