Phb Brinell Hardness Tester

Features ● Accurate and consistent test force, controlled by precision shear pin. Works in static type and hammer impact type and follows Brinell hardness test method. ● According to the similarity principle of Brinell hardness test, this tester has 1580kg test force, Ф7.26mm spherical indenter, F/D2=30. The test condition is equivalent to the commonly used 3000kg test force, Ф10mm ball condition. ● High accuracy and repeatability; tested by National Institute of Metrology with tolerance less than ±3%. The accuracy meets the requirements of ISO 6506 and is no lower than that of the bench Brinell hardness tester. ● Easy, quick and simple operation. Static type for testing medium and small size workpieces; hammer impact type for testing large workpieces. ● Only one inexpensive shear pin is consumed in each test. ● Good choice to replace Leeb hardness tester and Poldi type hammer impact hardness tester with lower accuracy. Technical Parameters Test Force:1580kg Tolerance of test force:< 0.5% Indenter: Ф7.26mm steel spherical suface indenter, (test range: 100-400HB);Ф4.0mm carbide spherical surface indenter (test range: 400-650HB) Accuracy:Meets the requirements of ISO6506 Error of static type: <±3%HB Error of hammer impact type: <±5%HB Test Range:100-650HB Application:Casting, forging and steel raw materials etc Application ● If the workpiece can be put into the C clamp, Static type is recommended for a more accurate test result. ● Hammer impact type tester should be compared with a bench Brinell hardness tester or static type tester.
