Jan 20, 2017

1, the use of weight directly loading, the A-K ruler, early test of accuracy is within 0.2%, total test precision is less than 0.1%; n, t-ruler test precision is less than 0.5%, total test precision is less than 0.25%.
2, the indentation depth measuring device with Germany HEIDENHAIN high accuracy grating, ensure the error is within 0.2 μ m.
3, the use of frame structure with good-looking and good rigidity. A-K ruler, ensuring frame deformation's influence on hardness value less than 0.3HR; n, t, and guaranteed frame deformation's influence on hardness is less than 0.6HR.
4, loading or unloading, smooth operation without noise;
5, PLC and touch screen control, the testing process automation;
6, the use of multiple protection, safe and reliable operation;
