TMTeck Magnetic Type Rockwell, Brinell & Rockwell Hardness Tester TMBR-500
Introduction
The world No. 1 Rockwell or Brinell & Rockwell hardness tester, capable of testing the hardness of metals by touching only one side of the test piece, designed according to the principle of both Rockwell and Brinell hardness testing.
The test head of the Rockwell or Brinell & Rockwell hardness tester is adsorbed on the surface of iron and steel by magnetic force, without giving support to the test piece.
The testing accuracy complies with ISO6508/ 6506 no lower than that of the relevant bench type hardness tester.
Suitable for testing the large-size work pieces which are assembled, unable to cut and inconvenient to move such as the large-size mold, steel plate, steel tube, steel structure, boiler, pressure vessel and metallic pipeline etc.
Fast and easy testing without sampling; any large work pieces can be tested with only one flat or curved surface available for holding the instrument.
The testing results meet the requirements of the product standards or drawings of most workpieces without conversion.
Can take the place of Leeb hardness tester of low accuracy in most cases.
Model TMBR-500 with the digital screen,can easy test and get test result.
