Electronic Brinell Hardness Tester
Product Description:
- Brinell hardness test is mainly used in hardness measurement for cast iron, steel products, nonferrous metals and soft alloys, etc. Besides it can be also used in hardness measurement for some non-ferrous materials, such as plastics, bakelite, etc.
- Brinell hardness test is to use a steel ball of a certain diameter to press on the substance surface to be tested with specified test force. Through the specific time of holding test force, remove it and measure impression diameter of test piece surface with reading microscope.It is Brinell hardness value to calculate average pressure (N/mm2) of the spherical area to be beard in steel ball impression Brinell hardness value.
