Electric Brinell, Rockwell and Vickers Three Way Hardness Tester
HMRV(D)-45D1
Electric Surface Rockwell & Vickers Hardness Tester
Main Features
- It has three hardness test methods of Brinell, Rockwell, and Vickers.
- Direct reading of dial hardness value.
- Automatic loading and unloading- keeping-unloading, simple operation, no artificial operation error.
- Stable performance, simple operation and convenient use.
- Optimized design of a mechanical structure, low electrical power consumption, linear small circular arc appearance.
- Strong structure, good rigidity, accuracy, reliability and durability, and high-test efficiency.
Application Range
- Rockwell: It is used to measure Rockwell hardness of ferrous, nonferrous metals and nonmetallic materials. It is suitable for measuring Rockwell hardness of heat treatment materials such as quenching and modulation.
- Vickers: Ceramics, steel, non-ferrous metals, non-metallic materials, carburizing layer, nitriding layer, electroplating layer. It is suitable for measurement of hardened layer and ultra-thin parts.
- Brinell: It is used to measure Brinell hardness of ferrous metals, nonferrous metals, nonferrous alloys, and powder metallurgy materials. It is widely used in metallurgy, forging, casting, bearing alloys.
