VKJ-BK7555
The VKJ-BK7555 is a backscatter X-ray inspection system engineered for large baggage and parcel screening in commercial environments. Featuring a spacious 755 × 555 mm tunnel, it integrates backscatter and transmission imaging technologies to provide comprehensive inspection coverage for oversized items, packages, and bulk shipments that exceed the capacity of standard tunnel scanners.
Backscatter and Transmission Integrated Imaging
The VKJ-BK7555 combines dual-mode imaging to deliver superior inspection results. The transmission imaging channel provides high-resolution penetration views of dense contents, while the backscatter channel excels at highlighting organic and low-Z materials. This integrated approach enables operators to perform thorough non-intrusive inspection without compromising throughput.
Material Differentiation Capabilities
- Organic-Content Screening: Backscatter technology is highly sensitive to organic materials, enabling operators to identify and differentiate organic contents from inorganic items with greater confidence.
- Multi-Energy Material Classification: Color-coded imaging based on effective atomic number assists operators in rapidly distinguishing between material categories during screening.
- Non-Intrusive Inspection: The combined backscatter and transmission approach allows comprehensive content assessment without physical unpacking, preserving package integrity and workflow efficiency.
