Hammer Impact Type Pin Brinel Hardness Tester Meter Steel Sclerometer PHB-1.


  • 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 1580 kg test force, Φ 7.26 mm spherical indenter, F/D2=30. The test condition is equivalent to the commonly used 3000 kg test force, Φ10mm 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
  • 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.
