PHB Brinell Hardness Tester

Product Description

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 ***0kg test force, Ф7.*6mm spherical indenter, F/D2=*0. The test condition is equivalent to the commonly used ***0kg test force, Ф*0mm ball condition. ● High accuracy and repeatability; tested by National Institute of Metrology with tolerance less than ±3%. The accuracy meets the requirements of ISO ***6 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:***0kg Tolerance of test force:< 0.5% Indenter: Ф7.*6mm steel spherical suface indenter, (test range: ******0HB);Ф4.0mm carbide spherical surface indenter (test range: ******0HB) Accuracy:Meets the requirements of ISO***6 Error of static type: <±3%HB Error of hammer impact type: <±5%HB Test Range:******0HB 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.
