TT-B3000A Advanced Three-indentor Digital Brinell Hardness Tester

Precise structure design, load of test force is controlled by sensor.
Test process is controlled by the CPU, automatic switching between objective and indenter.
The location of switching adopts mechanical and electronic double matching, makes the location precision higher.
Apply to the measurement of cast iron, nonferrous metal and alloy material, various annealing, hardening, and tempering steel, especially 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 the 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 the requirements of the client, it can be equipped with CCD indentation automatic measuring device or video measuring device.
