This instrument is mainly composed of a pencil holder and a test bench, and the pencil holder and the column form a four-link structure, which ensures that the weight of the weight acts perpendicularly on the intersection of the pencil lead and the test bench, and makes the pencil and the test bench at an angle of 45 ° and remains unchanged. The test bench can be moved horizontally and longitudinally, and the paint sample can be fixed with it, and the sample will be scratched in the direction of the scratch, and the pencil will draw the corresponding trajectory on the test piece. Different pencils are used to draw different marks, and the hardness value of the coating film can be determined.
