Overview
The LANDTEK HT-6510P Pencil hardness tester is a mechanical scratch hardness tester, which is strictly designed according to national standards and is suitable for the Hardness detection of paint film coatings in industries such as Coating paints. The instrument uses three points to contact the tested surface (two points are the wheel and one point is the pencil lead), uses the pencil to form a 45 ° angle with the test surface, and pushes and slides to make pencils with different Hardness values scratch at different depths on the surface of the paint film to judge film Hardness.
Features
1. Pencil scratch method for measurement of paint film Hardness, economical and fast, widely used internationally
2. Standard 13 Chinese pencils, Hardness range from 6B to 6H
3. Three-point contact design (two points for the wheel, one point for the pencil lead) to ensure test Stability
4. Production and design in strict accordance with national standards
5. Load adjustable: 500g, 750g, 1000g
6. The main materials are stainless steel and iron, with strong durability
Principle
The HT-6510P Pencil hardness tester uses the pencil scratch method to measure the paint film Hardness. The instrument uses the pencil to form a 45 ° angle with the test surface, and the pencil lead is engraved on the paint film surface by pushing and sliding.
Applications
Laboratories or construction sites for industries such as coatings and paints
Steps
1. Install the pencil on the hardness gauge
2. Adjust the pencil to a 45 ° angle with the test surface
3. Select the appropriate load (500g, 750g or 1000g)
4. Push the Pencil hardness tester to slide on the surface of the paint film
5. Visual observation of film scratch depth
6. Determine film Hardness based on scratch results
Notice
• Make sure the level indicator is adjusted correctly before use
The pencil lead should be kept sharp
• The driving direction should be consistent
• The test surface should be flat and clean
• Select the appropriate pencil according to the test requirements Hardness
• Regularly check the tightness of the wheels and fixing screws
