Sinowon portable hardness tester design for measuring

◆ Auto-stage, Auto-Turret, Auto-measurement and Vickers testing system; 

◆ Loading-force: Precise dead weights ensures the loading force system reliably and precisely;

◆ Optical-path: High-resolution optical microscopy path makes image of indention sharply and excellent; 

◆ Auto-Turret: the switch position of Vickers indenters and 10X/40X objectives is repeatable and accurately; 

◆ Auto-stage: it is driven by precise step motor with large travel size 100x100mm and heavy load ability ; 

◆ Auto-Measurement: automatic hardness testing and measurement software：3A can control hardness tester and data communication, includes the switch of 10X, 40X objectives and Vickers indenter, auto loading, dwell and unloading, single or multiple indentation, set step distance, movement mode, auto record indentation dialog line and hardness value, auto generate CHD depth and hardness curve, error statistics, test times group statistics, generate Excel and Word format report. 

Vickers method is based on an optical measurement system, it specifies a range of light loads using a diamond indenter to make an indentation which is measured and converted to a hardness value. It is very useful for testing on a wide type of materials, but test samples must be polished to enable measuring the size of the impressions. A square base pyramid shaped diamond is used for testing in the Vickers scale. "Macro" Vickers loads can range up to 50 kg or more.

Macro Vickers hardness methods are used to test on metals, and composites - almost any type of material. Since the test indentation is small in a Vickers test, it is useful for a variety of applications: testing very thin materials like foils or measuring the surface of a part, small parts or small areas, measuring individual microstructures, or measuring the depth of case hardening by sectioning a part and making a series of indentations to describe a profile of the change in hardness.
