KH-260plus
KH-260plus Technical Specifications
Feature |
| lPen type design, self contained (Impact device and display integrated): no cables. |
lThe unique large-screen OLED color display（1.77-inch OLED Screen）integrated hardness tester in the world |
lDouble coil design for impact device , no A/D conversion error, to get the speed ratio directly with high repeatability |
lInterchangeable D impact device (standard) /DL impact device (optional) can achieve one unit dual use; can be used in the restricted area measurement. |
| lWith battery compartment, battery can be replaced. Using standard AAA Lithum battery. |
lHighly accuracy in any impact direction (360°), automatically identify impact direction and gravity compensation. |
| lEasy Operation, the four soft keys above the screen achieve the various functions. |
Working Principle |
The impact body impacts into the work piece and rebounds back. The rebound and impact velocities are measured at the 1mm point from the work piece in the following way: the integrated permanent magnet will produce directly proportional voltage with the impact velocity. The Leeb hardness values are calculated by the following formula:
