Portable surface Rockwell hardness testerComposed of a host and a support base, it can be used on a desktop or carried to the workshop for on-site use. The indentation is very small and has no effect on the use of most workpieces, which can be considered as non-destructive testing. Used for testing thin small parts, such as thin plates, thin tubes, thin shafts, small balls, small stamped parts, and work with very small support surfaces. Used for testing workpieces that require minimal indentation. Can replace the expensive and inconvenient Vickers hardness tester. Traceable standard hardness block. The indenter that has passed the standard Rockwell hardness tester inspection. The force measuring instrument used for verifying the test force can be traced back to the national sub standard.
