Hardness Testers

Hardness testers measure a materials' resistance to indentation.  Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth or projected area of the indentation. More simply put, when using a fixed force (load) and a given indenter, the smaller the indentation, the harder the material. Indentation hardness value is obtained by measuring the depth or the area of the indentation using one of many different test methods.  Hardness testers use one of several types of scales for determining the hardness of a sample.  These include Brinell, dynamic rebound, coating or nanoindentation, Rockwell, Vickers and Knoop and ultrasonic.  Methods include macro, micro and superficial testing.
