SALIENT FEATURES
These machines come in two basic versions.i.e.Pure Vickers and Vickers cum Brinell. Load range for pure Vickers is from 1 kg. to 120 kg and for Vickers cum Brinell, 1 kg to 250 kg |
|
|
| |
| GENERAL : |
1. |
These machines are suitable for checking Vickers or Brinell Hardness of Steel and other metals. |
2. |
Loads are applied with dead weights and are selectable with push buttons. |
3. |
Measurement of Diagonal / Diameter of indentation is done with the help of built in optical system with with built-in micrometer scale. |
4. |
After taking the indentation on work piece , objective lens is automatically swiveled in position and indentation image appears on the focussing screen fitted in front of the machine. |
5. |
Loading cycle is started with Push Button in the front where-as unloading is done manually by hand lever. |
6. |
All models i.e.KVM-120, KVM-120S, KVM-250, KVM-250S confirm to IS 1754 & BS 427 for Vickers & IS 2281-1983, BS 240,ASTM-E-10 for Brinell Hardness. |
