A hardness tester is an instrument used to measure the hardness of a material by applying a standardised pressure or force to form marks or deformations on the surface of the material, and thus measuring the magnitude of these deformations to determine the hardness of the material. The following is a brief introduction to hardness testers:

Types and principles: There are various types of hardness testers, such as Rockwell hardness testers, Brinell hardness testers, etc. Each is based on a different principle and method of quantification, but they all follow the same basic principle of applying a force and measuring the resulting deformation.

Applications: Hardness testers are widely used in the fields of materials science, engineering and quality control, etc. They are important for assessing the strength, wear resistance and service life of materials, and guiding the product design and manufacturing process.

Development trend: With the advancement of science and technology, hardness testers are developing towards higher measurement accuracy, wider range of application and more convenient operation interface.
