           Poldi Magnifier

          APPLICATION

          The hammer type Poldi impact hardness tester is useful for simple and quick determination of Brinell hardness of metals such as steel, Cast Iron, Brass, Aluminium, Copper etc. Due to easy handling and manoeuverability, this tester is most suitable for testing heavy castings and other components.

          PRINCIPLE

          Load is applied to the specimen and a standard test bar in a linear direction through a special Brinell Ball of 10 mm dia. by a hammer blow. With the impact load being consistent, the extent of indentations obtained on the specimen and the test bar depend on their hardness, harder material gives less depth of indentation. The two diameters of indentations are measured by a special “Magnifiscope" measuring magnifier supplied with the tester.
