How to distinguish between a good and bad hardness tester?

It belongs to the category of metrological testing instruments and plays an important role in ensuring product quality and stopping failure analysis. Therefore, choosing a good hardness tester is a key issue for users.
A true hardness tester complies with national standards and norms and possesses interchangeability and consistency. Although relevant departments in China have formulated national standards, some manufacturers' technical capabilities fail to reach the level of production that complies with the standards. Therefore, they adopt corrective methods to produce hardness testers. Although their products are also named hardness testers, they are far from true hardness testers. Originally inaccurate hardness testers can also meet the requirements of accurately testing hardness blocks after correction. Therefore, for users to choose a good hardness tester, they need to truly understand the characteristics of hardness testers.
