Instrument:Shimadzu HMV-G31
Manufacturer: Shimadzu
General Description: The Shimadzu HMV-G series performs microindentation hardness testing using Vickers or Knoop indenters. A precision loading mechanism applies calibrated forces through a diamond indenter to create controlled impressions in material surfaces. An integrated camera system captures images of resulting indentations for automated diagonal measurement. Software calculates hardness values from indentation dimensions according to standard test methods. Motorized stages enable automated multi-point testing across sample surfaces. The system supports various test forces suitable for characterizing thin coatings, surface treatments, and small-scale material heterogeneity. Applications include coating characterization, case depth measurement, heat treatment verification, and microstructural hardness mapping across metallurgy, materials research, and quality control operations.
