DHV-1000Digital microhardness tester
Main features:
This machine should be equipped with 20x and 40x objective lenses that can participate in measurement, expanding the measurement range and making it widely applicable.
● 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.
Use a cold light source on the light source. Long service life.
Application scope
——Black metal, non-ferrous metal IC thin film, surface coating, laminated metal;
——Glass, ceramics, agate, gemstones, etc;
——Hardness testing of depth and gradient of carbonization layer and quenching hardening layer.
