Technical Classification and Characteristics of Wall Scanners

Wall scanners can be classified into various types based on different technical principles, each with unique features and applicable ranges. The main technical classifications include electromagnetic, ultrasound, and radar scanners.

1. Electromagnetic Scanners:
   • Characteristics: Primarily used to detect metal objects such as rebar and electrical wires. They are fast and easy to operate.
   • Applicable Range: Widely used in construction and renovation fields, suitable for quickly locating metal pipelines within walls.
2. Ultrasound Scanners:
   • Characteristics: Capable of detecting objects of different densities within walls, including non-metallic objects and voids. They offer high precision but require more operational expertise.
   • Applicable Range: Suitable for scenarios requiring high-precision detection, such as building inspections and scientific research.
3. Radar Scanners:
   • Characteristics: Can obtain detailed images of the wall’s interior, with deeper detection capabilities and the ability to identify various types of objects. They are more expensive and complex to operate.
   • Applicable Range: Widely used in engineering surveys, archaeological investigations, and security inspections.
4. Integrated Scanners:
   • Characteristics: Combine multiple detection technologies to comprehensively analyze the complex structures and objects within walls, providing more thorough detection results.
   • Applicable Range: Suitable for large-scale engineering projects and applications requiring comprehensive detection.
