Intro:
Tester handheld pencil hardness also known as scratch pencil hardness tester.
Hardness is an important physical property of lenses and coatings, as abrasion resistance, abrasion resistance, abrasion resistance, scratch resistance, impact resistance, film retention and difficult to wash. Therefore, the hardness of the film is necessary to evaluate the performance of the lens and coating.
The hardness of the lens and film can be measured with this convenient instrument.
Utensils are mainly made of pencil holder and test bench. The pencil holder and column consists of 4 interlocking rods. This ensures that the weight of the weight is perpendicular to the point of the pencil core and the test bench, leaving the pencil with a test bench at a 45 degree angle and it will not change.
The test bench can be moved horizontally and longly to correct the paint pattern and slide the pattern towards the scratch. Compatible tracks on pencil mark specimen
You can decide the hardness value of the coating by changing different pencils and different marks.
