Application:
Analog Brinell, Rockwell, Vickers Hardness Tester NOVOTEST TB-BRV implements direct Brinell,.Rockwell and Vickers methods of hardness testing in accordance with ISO 6508, ASTM E10, ASTM E92, ASTM E18.
The device allows user to perform:
- hardness testing of ferrous metals (steel, cast iron, low carbon steel and tempered steel, etc.)
- hardness testing of non-ferrous metals (alloys from aluminum, copper etc.)
- hardness testing of hard alloys, carbonized and chemically treated layers
Advantages
- Easy in operating and servicing
- Multi-functional instrument in its class. User can measure hardness in various scales (methods) and have no problems with hardness measurement in a wide range – from very soft materials up to some of the hardest materials
- Special movable table which allows user to measure the diameters of prints without removing the sample from the device
- Special stand for the microscope, which significantly simplifies operating the device
- Built-in high precision microscope with backlighting
- An electric actuator – the main test load is completely automated
- Allows user to maximize the efficiency of the using portable hardness testers. Using this device user can verificate standard hardness test blocks and calibrate portable hardness testers according to any of the most popular hardness scales.
