This category encompasses specialized equipment for detecting and analyzing foreign matter contamination and impurities in quality control of products and raw materials at manufacturing sites. It includes metal detectors, X-ray inspection systems, near-infrared spectroscopy analyzers, foreign matter sorting machines, and other devices used in food manufacturing, pharmaceutical production, chemical industry, and electronic component manufacturing for quality assurance and safety assurance. These critical inspection and analysis equipment groups detect minute foreign matter and internal impurities that are difficult to identify through visual inspection with high precision, contributing to improved product reliability and reduced recall risks.
