Product Details

u Instrument Description:

l Precise structure design,load of test force is controlled by sensor.

l 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.

l 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. .

l 10 level of test force, 13 Brinell hardness test scales, free to choose;

l With three indenters for automatic measurement;With two objectives;

l Automatic switching between the objective and the indenter according to the scale;

l Can preset the test force dwell time and adjust intensity of light source;

l Can show the indentation length, the hardness value and the number of measurements

l Choice of conversion between each scale of hardness values; test result can be printed;

l According to requirements of client, it can be equipped with CCD indentation automatic measuring device or video measuring device.
