● Precise structure design,load of test force is controlled by sensor.
● Test process is controlled by CPU, automatic switching between objective and indenter. The location of switching adopts mechanical and electronic double matching, makes the location precision more high.
● Apply to the measurement of cast iron, nonferrous metal and alloy material, various annealing, hardening and tempering steel, especially the soft metal such as aluminum, lead, tin etc. .
● 10 level of test force, 13 Brinell hardness test scales, free to choose;
● With three indenters for automatic measurement;With two objectives;
● Automatic switching between the objective and the indenter according to the scale;
● Can preset the test force dwell time and adjust intensity of light source;
● Can show the indentation length, the hardness value and the number of measurements
● Choice of conversion between each scale of hardness values; test result can be printed;
● According to requirements of client, it can be equipped with CCD indentation automatic measuring device or video measuring device.
