TG-M704 Magnetic Crawler C-scan Corrosion Thickness Measurement System with Remote Control and High-Strength Permanent Magnet Wheel for No Scaffolding Needed

This advanced system enables rapid detection of high-altitude wall thickness corrosion through remote control, eliminating the need for scaffolding, surface polishing of anti-corrosion layers, or any couplant.

• Uses rare-earth high-strength permanent magnet wheels for secure attachment - will not fall even during power failure
• Performs horizontal, vertical, and inverted multi-attitude motions on ferromagnetic surfaces
• Equipped with electromagnetic ultrasonic thickness measurement probe for rapid corrosion screening and localization
• Intensive and accurate scanning of suspected corrosion areas quantifies wall corrosion
• Standard A, B, and C scan displays for comprehensive thickness analysis
• Integrated video camera for real-time surface inspection monitoring
• Remote control operation with preset scanning tracks for automated scanning

• Integrated front-view and rear-view dual cameras for real-time monitoring
• Strong magnetic suction with vertical upward load capacity up to 16kg
• Multiple movement postures: vertical, horizontal, inclined, and inverted
• High motion precision with millimeter-level programmed step detection
• Compact design with small turning radius for maneuverability
• Distance positioning (error ≤30mm) with optional defect marking
