Working Principle
The MG200 operates by illuminating X-ray films placed on the yakeli observation screen using a high-intensity LED light source. The light passes through the film, revealing internal structures and flaws in the material. The viewer’s consistent and bright illumination ensures clear detection of flaws, supporting precise assessment and quality control in accordance with NDT standards.
