The portable hardness tester is a handheld testing instrument primarily used for testing the hardness of metallic materials, manufactured by Times Opple Technology Co., Ltd.
This equipment is suitable for on-site testing of installed machinery, mold cavities, heavy workpieces, and the inner and outer walls of steel pipes, featuring portability and flexible operation. The portable hardness tester integrates multiple testing methods such as Leeb, Brinell, Rockwell, and Vickers, supports automatic conversion of 7 hardness values, and conforms to international standards such as GB/T230 and ASTM E110. Its main body includes an indenter, a force measuring device, and a display screen. The test force error is less than 0.5%, and the measurement error of the Rockwell model is controlled within ±1.5HR [2-4]. Using dynamic impact or static loading methods, it can test slender, irregularly shaped workpieces, and some models achieve on-site Brinell hardness testing through a hydraulic system. The equipment has the advantages of small size, light weight, and fast testing speed (completed in seconds), and is widely used in materials research and development, machinery manufacturing, aerospace, and quality control.
