Even narrow widths or small diameter scratches that are usually invisible to the eye can be confirmed visually!
"Penetrant testing" is a method for detecting cracks and other openings on the surface of test specimens through the capillary action of liquids. The penetrant is allowed to seep into the surface of the test specimen, and after removing the excess penetrant, a developer draws the penetrant that has seeped into the cracks back to the surface, allowing for detection of the flaws. Since a crack pattern that is enlarged compared to the actual dimensions of the flaws is formed, even narrow or small diameter cracks that are normally not visible to the naked eye can be confirmed visually. 【Features】 ■ Detects cracks and other openings on the surface of the test specimen ■ The developer draws the penetrant that has seeped into the cracks back to the surface, allowing for detection of the flaws ■ An enlarged crack pattern compared to the actual dimensions of the flaws is formed ■ Even narrow or small diameter cracks that are normally not visible can be confirmed visually *For more details, please refer to the PDF document or feel free to contact us.
