Hardness Tester FAQ
1. What is a hardness tester?
A hardness tester is a device used to determine the hardness of a material by measuring its resistance to deformation, 침투, or indentation. It is widely used in industries like manufacturing, 자동차, 항공우주, and plastics to ensure product quality and compliance with standards.
2. How does a hardness tester work?
Hardness testers apply force using an indenter or probe onto the surface of a material. The depth or size of the indentation, or the rebound of the impact, determines the material’s hardness. Each type of tester (Leeb, 지주, Barcol, etc.) follows different principles for specific material types.
