The Sacrificial Anode Inspection Device is a highly tailored industry product developed after extensive consultation with multiple teams of cathodic protection (CP) stake inspection personnel. It addresses longstanding pain points of manual inspections, such as cumbersome testing procedures, complex data recording and analysis, and high training costs. During inspection tasks, users simply scan the QR code on the device’s surface with a smartphone to launch a mini-program, enabling one-touch automatic measurement, recording, and analysis of CP parameters—including pipe-to-soil potential, instant-off potential, and anode current—truly achieving zero-training, one-button operation.
