HR-150A Ⅱ Rockwell hardness testerDetailed product description：

The HR-150A II Rockwell hardness tester uses a fully imported LCD digital display instead of a pointer dial, eliminating reading and operation errors, improving display accuracy and repeatability accuracy. The machine has a novel appearance and is easy to operate. Suitable for Rockwell hardness testing of metallic materials. The speed of applying the test force is adjusted by the buffer, and the transformation of the test force is obtained by the conversion of the variable load handwheel, which has the characteristics of easy operation, stable performance, and wide use.

Principle: Rockwell hardness is suitable for measuring the hardness of various metal materials. Its testing principle is to press the indenter into the surface of the specimen under the action of the initial test force and the total test force, remove the main test force, and measure the residual depth of the indentation when retaining the initial test force.
