ARUN MAKE Portable Hardness Testing Machine

Listing ID #3229204

'ARUN' Portable Rockwell Hardness Tester is developed to meet the demands of a light weight instrument which can be used to carry out tests by a universally recognised method of Hardness testing.

This hardness tester can be used in variety of applications and is readialy adjustable to a wide range of sizes and shapes which are difficult to test in a standard table model hardness tester.

The machine is designed for carrying out Rockwell tests comparable to table model hardness tester because, the basic things, such as shape of penetrator, method of penetration, measurement and loads are same in both systems.

The photograph on the back side 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 indicated on the loading dial indicator (1). Besides this loading dial indicator, there is one penetration measuring indicator (14) which measures the actual penetration of the penterator into the test specimen is read directly on this indicator.
