-
- Highly sensitive test method for the detection of longitudinal defects on steel bars
-
- No coupling liquid
-
- Quick to install and easy to operate
-
- Reliable and reproducible test results
-
- Automatic marking and sorting of the tested bars
-
- High production speeds
-
- Several reporting options
AC flux leakage principle

Magnetic Flux Leakage Testing (MFLT)
-
- Based on automated Flux leakage inspection system.
-
- Uses high energy A.C. Magnetic Leak fields for detection of longitudinal flaws.
-
- Real time display of ongoing inspection.
- Fully automated defective marking & sorting of the material.
