Description

Digital Brinell hardness tester provides automatic electronically controlled values of loading, which allows user to simplify operations with the device, and significantly increases the accuracy and productivity of testing. Bench Digital Brinell Hardness Tester NOVOTEST TB-B-CM has high measuring accuracy, wide range of applicability in measurements.

Digital Brinell Hardness Tester NOVOTEST TB-B-CM has fully automatically test cycle: loading, dwell and unloading.  As a result, the operator errors don’t influence on measuring.

Motorized indenter and electronic control system allow making measurements of high accuracy. Absence of mechanical weighs reduce problems of friction and vibration sensitivity of the tester.

Also, Digital Brinell Hardness Tester NOVOTEST TB-B-CM is equipped with high-precision optical microscope for imprint-size estimation.

Imprint diameter is measured manually by the built-in microscope, then operator inputs data and see ready hardness value on LCD screen. Operating is very easy, fast and convenient, no manual tables are used.

Application

Brinell hardness tester is used for:

  • hardness testing of metal products by the Brinell scales;
  • hardness testing of metals with different properties without additional calibrations;
  • coarse-grain metal materials (cast iron, casted parts, non-ferrous metals and alloys);
  • non-hardened steel;
  • various tempered steels, hardening and tempering steels;
  • products from soft metals (pure aluminum, lead, tin) and soft alloys;
  • quality testing of heat treated metal parts;
  • verification of calibration hardness test blocks;
  • production of hardness test blocks, which can be used for calibration of portable hardness testers.
