On September 27, Gelonhui reported that Tsinghua Tongfang (600100.SH) stated on the interactive platform that multiple security inspection technologies and products independently developed by Tsinghua Vision are suitable for detecting trace explosives in electronic products. Computer tomography imaging systems, channel X-ray inspection systems can provide clear three-dimensional and two-dimensional X-ray images, showing the internal structure and characteristics of the inspected items (such as electronic products), and detecting explosives or detonators. Mass spectrometry analysis technology, ion migration spectrum analysis technology, as trace detection solutions, can accurately detect and identify various explosives at the nanogram level; generally, trace explosives adhered to the inspected items can be detected and identified by wiping sampling the inspected items. In mainstream security inspection applications such as civil aviation, rail transportation, and important facilities, Vision Security Inspection products, with advanced security inspection technology and detection performance, excellent quality and reliability, professional overall security inspection solutions and services, have obtained a leading market share. As the only domestic manufacturer with multiple security inspection technology products certified by the global civil aviation security inspection product authority including China Civil Aviation, Europe ECAC, France STAC, United Kingdom DfT, Vision can provide trustworthy high-quality security inspection products and solutions.
