Test, Measure & Inspect By GLTL

• Main Function The hardness of coating film is a necessary index for quality identification in coating manufacturing and coating application (coating table) industry. Pencil scratch test for film hardness is a widely used test method in the world since 1980s.
• Wide Application It is applicable to film hardness test. The instrument is mechanical, three points contact the tested surface (two points are wheels and one point is pencil core). It always ensures that the tested film forms an included angle of 45 degrees, and pushes the instrument to move horizontally with force, so as to complete the test process and determine the resistance of the film to deformation.
• Wide Application This instrument is designed and manufactured in accordance with the manual operation method in Article 2 and 3 of the national standard \"pencil test method for film hardness\" GB6379-86. The instrument can be used in the laboratory, can also be applied to the construction site, and can identify the hardness of the film in any direction.

• 0.02mm Accuracy Alloyed Electroplating Chrome Vernier caliper 0-150mm 0-200mm 0-300mm range Locking screw for holding measurement.
• Surface chrome plating, with sufficient hardness and corrosion resistance.
• Some people think that this mechanical caliper is not easy to read data, just like a needle watch and an electronic display watch, it is just a habit. This kind of mechanical caliper is the most suitable for the bad working environment without malfunction, and the precision deviation is not easy to occur.
• Depth Gage can measure the depth of holes, steps and columns more accurately.
• A safe protective package to ensure that it is not vulnerable to impact damage.
