BEVS 3168H adopts a new operating software and it is fitted with a 10-inch high-definition touch screen, which presents users with the test results, such as particle size distribution graphs, scratch distribution graphs, etc., providing strong support for R&D and quality control.

Pencil hardness--resistance of the surface of a paint film to marking, or the formation of some other defect, as a result of the action of a pencil, with a lead of specified dimensions, shape and hardness, which is pushed across the surface.

The aging of materials is influenced by solar radiation, temperature, water and other factors. Therefore, a more comprehensive simulation of the actual environment in which the material is used can lead to results with better correlation.
