Test principle and method
Elastic wave computer tomography (CT)
In the medical field, CT (Computer Tomography) is a very effective non-destructive testing technology. The principle of elastic wave CT we developed is basically the same as that of medical CT. The difference is that the medium used is elastic wave instead of X-ray. The parameters used are wave speed, not attenuation.
Railway concrete structure scanner
Powerful, intuitive results: meet the test requirements of railway concrete structural defects; and have a wealth of graphic image processing functions;
Advanced technology: It uses impact elastic wave and vibration as test media, and is compatible with various domestic and foreign technologies and our original technology. It has the advantages of high test accuracy and wide application range.
Reliable performance: The main components are imported from the United States and Japan, with high reliability and durability.
Technical support: a large number of engineering applications, with strong technical support capabilities;
Easy to operate: touch screen and remote control operation can be double-selected, and can also be tested by one person with high efficiency.
