TB 5004, TB 5004-03

Semi-automatic devices for measuring the hardness of metals according to the Brinell method

Devices are designed to measure the hardness of metals in two modes:

  1. According to the Brinell method in accordance with
    GOST 9012. Measurement of the diameter of the print using a microscope MPB-3.
  2. The depth of the restored print with the ability to sort products into hardness groups. It is carried out using the built-in arrow indicator with pointers ( TB 5004 ) or an electric sensor with a personal computer (laptop) and a program for mathematical processing of results
    (for TB 5004-03).
  3. Dismantling is possible using one of two measuring bases: the surface of the table of the device or the surface of the part (using a special emphasis, supplied by special order).

    Devices — stationary, desktop.

    The drive is electromechanical, the measurement cycle is automatic.

    Type approval certificate of SI ROSSTANDARD of RUSSIA No. 44527.
