Economic Portable Hardness Tester with  1580Kg Test Force And 100-650HB Test Range

Characteristic:

PHB-1 hammer impact type tester should be compared periodically with a bench Brinell hardness testr or static type tester

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, 7.26mm spherical indenter, F/D2=30. The test condition is equivalent to the commonly used 3000kg test force, 10mm 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 work-pieces; hammer impact type for testing large work-pieces.
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.
