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

• Accurate and consistent test force, controlled by precision shear pin. Works in static type and hammer type and follows Brinnel hasrdness test methods.
• 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.
