Pencils of different hardness are used to test the pencil hardness of the coating. In the experiment, a force of 0-10 N was applied to a pencil tilted at an angle of 45 degrees, and the coating was tested at a constant and steady speed. In order to obtain a stable and continuous force and speed, the HT200 has a built-in motor to ensure the accuracy and repeatability of the test.
-Running mode: forward or backward
-Running time: 1-60 seconds setting
-Apply pressure: 0-10N
-Eliminate possible effects caused by instrument startup, and start timing two seconds after startup
-The sound prompts 30 seconds after the operation stops and the following observation tests can be carried out
