TG-M704 Magnetic Crawler C-scan Corrosion Thickness Measurement System with 0.04mm Accuracy and 2~120mm Range for Steel No Couplant Needed

The TG-M704 Magnetic Crawler C-scan Corrosion Thickness Measurement System enables rapid detection of high-altitude wall thickness corrosion through remote control. This innovative system eliminates the need for scaffolding, surface polishing of anti-corrosion layers, and couplant application.
