Beschichtungsfilm-Kratztester-Kit Mit 13 Bleistiften, 3-in-1-Bleistifthärteprüfer, Bleistiftspitzenlast 500 G/750 G/1000 G, Verwendet In Labors Oder Auf Baustellen, Für Kratzfestigkeitstests

- The pencil hardness tester is suitable for testing the hardness of coatings. The instrument can be used in laboratories or construction sites, and can identify the hardness of coatings in any direction.
- The pencil hardness tester is made of stainless steel, which is durable and has a smooth surface.
- Load weight: 500g/750g/1000g; measurement angle: 45° (between the pencil and the surface to be tested); scratch speed: about 1 mm/s; 13 pencils: 6B-HB-6H.
- The pencil hardness tester adopts mechanical measurement, maintains three-point contact with the coating (two wheels, a pencil lead), the pencil is at a 45-degree angle with the test surface, pushes the instrument to slide, and draws a corresponding track on the coating with a pencil. The hardness value of the coating can be determined in the changes of different pencil marks.
- The instrument is mechanical and contacts the surface to be tested at three points. The two sides are wheels and one point is the pencil lead, which always ensures that the coating to be tested forms a 45-degree angle. Push the instrument horizontally with force to complete the test process and measure the ability of the coating to resist deformation.
