Even narrow scratches or small diameter defects that are usually not visible to the naked 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 the detection of the flaws. Since a magnified pattern of the actual flaw dimensions is formed, even narrow or small-diameter flaws that are normally invisible 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 flaw detection ■ A magnified pattern of the actual flaw dimensions is formed ■ Even narrow or small-diameter flaws that are normally invisible can be confirmed visually *For more details, please refer to the PDF document or feel free to contact us.
