The instrument adopts a unique and precise design in mechanics, optics, and light sources, making indentation imaging clearer and measurement more accurate. This machine should be equipped with 20x and 40x objective lenses that can participate in measurement, making the measurement range larger and the application more extensive. Quantity microscopic configuration, the instrument is equipped with a digital measuring microscope, which does not require checking the table or inserting the length of the indentation diagonal. It can directly display the test method, test force, indentation length, hardness value, test force holding time, measurement times, etc. on the liquid screen. There is a threaded interface that can connect digital cameras and CCD cameras. It is the first and only light source to use a cold light source. The service life is 100000 hours. It is representative and progressiveness among similar products at home and abroad. |
