Portable Metal Magnetic Memory Tester

The COBE metal magnetic memory tester is mainly used to detect the most dangerous parts and workpieces in the stress concentration zone of heavy industrial equipment.
The portable metal magnetic memory tester can realize rapid detection because there is no need to clean the surface of the workpiece before testing.
It can be used for flaw detection and stress detection for in-service metal parts in industries such as nuclear power, petrochemical, aerospace, etc. It can also be used to carry out flaw detection, analysis and evaluation of various ferromagnetic pipes. Meanwhile, this tester can test boiler pipes, petrochemical pipelines, pressure vessel pipes and oil storage equipment.
