Portable Hardness Testing Machine

Portable Hardness Testing Machine is developed to meet the demands of a light weight instrument which can be used to carry out by a universally recognized method of hardness testing.
Rockwell Method

This hardness tester can be used in variety of applications and is readily adjustable to a wide range of sizes and shapes which are difficult to test in a standard table model hardness tester.
The machine as designed for carrying out Rockwell tests comparable to table model hardness tester because, the basic things, such as shape of penetration, measurement and loads are same in both systems.

The above photograph gives the general arrangement of the hardness tester.
The system carries a weight bar (8) pivoted at central point. When the load is applied by the loading screw (9), at one end of this weigh bar, it is deflected and the other end of this bar carrying penetrator forces down into the test specimen. This deflection of weight bar which is proportional to the applied load is indication of the loading dial indicator (11). Besides this loading dial indicator, there is one penetration measuring indicator(14) which measures the actual penetration of the penet
