Micro Vickers hardness testing instruments offeran easily, quality and durability solution for a wide range of microhardness scale testing. Steel, ferrous metal, non-ferrous metal, metal foil, hard alloy, metal sheet and microstructure. Carbonized layers and quench hardened layers, electroplated layer, and coatings. Glass, chip, ceramic, precious stones, etc. Only input the indentation diagonal, can get the hardness value automatically on the screen. Show the test mode, test force, test scale, dwell time, test result on the screen directly. Automatic, high speed and motorized turret or manual turret. High precision focus system ensure accurate measurement5.Adjustable LED illuminator. Integrated high speed thermal printer. One-time casted aluminum shell, more stable. Optional Knoop testing upon request. Optional CCD Camera & auto measurement system upon request. Optional LCD big screen for simultaneous observation of many people upon request. We are able to research &develop &design &produce independently, we also provide accessories replacement and maintain upgrade services for life-time for all machines.
