The hammer typePoldi Hardness Testeris suitable for measuring the Brinell Hardness of Steel, Cast iron, Brass Aluminum, Copper etc. This Poldi Hardness Tester is used to test parts where bench type model is not useful. This type of machine is most ideal and simple for foundries, Workshops, Engineering Colleges, Technical Institutions etc.
Principle:

• The load is applied by a hammer blow on the specimen and a standard test bar in a linear direction through a hardened steel ball of 10 mm dia.
• The impact load on both is the same.
• The extent of indentation on the specimen and the test bar depends on their hardness.
• The two diameters of indentations on test bar and specimen are measured by a magnifier supplied along with the tester.
• The hardness of the specimen can be determined, by referring got the chart supplied with the machine.

product details:

hardness testing machines model trs, trb, trb-250, tsm are manually operated. All these models are suitable for testing

hardness of metals and alloys of all kinds of hard or soft, whether flat, round or irregular shape. These tester are simple in design and easy to operate, to sensitive and accurate.
