Abstract: With the development of science and technology, the test accuracy, automation level, ease of use, etc. of the hardness testing equipments have been greatly improved. Some of the new and smart features of the hardness testers in hardened layer test, multiple samples test as well as some special testing requirements were introduced, and the benefits and conveniences of each feature were also illustrated. It is expected that these features could give a general idea of the future trend of hardness testers and provide reference for the purchase of high quality hardness testers.
