The AS-120P Pencil Hardness Tester is developed by An Miao according to the standard. It uses the pencil scratch method to determine the coating film hardness of the organic coating on the substrate in a fast and economical way through a drawing lead or pencil lead with known hardness. AS-120P pencil Hardness Tester is widely used in the development research and industrial production of coatings. AS-120P Pencil Hardness Tester can be used not only in the laboratory, but also in the construction site.

The AS-120P Pencil Hardness Tester is mechanical, with three points in contact with the surface to be tested (two points are the wheel, and one point is the lead core). Always ensure that the pencil is at an angle of 45° with the test surface. Push the instrument to slide by hand, and the pencil will be on the paint film. Draw the corresponding track on it. Use different pencils to draw different marks, based on which the hardness value of the coating film can be determined.
