The Mitutoyo HM 220 D is a Microbickers hardness tester.[1]
What it is
The Mitutoyo HM 220 D is a Microbickers hardness tester. The HM 220 D is manufactured by Mitutoyo.[1]
How it works
General reference — not yet source-verifiedHardness testers of the Microbickers class operate on the Vickers indentation principle. The instrument presses a diamond pyramid indenter into the surface of a specimen under a controlled small load. A built-in optical microscope measures the diagonal of the indentation left in the material. The hardness result is computed from the applied load and the measured indentation size.
