INTRODUCTION

Magnetic Type 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.

APPLICATION

It is suitable for on-site testing the large-size iron and steel work pieces. 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.

(a)                 Large-size steel plate, mold, steel structure, work pieces with enough flat surface. The minimum surface requirement is 180mm X 60mm.

(b)                 Steel tube, boiler, pressure vessel and metallic pipeline etc. Only if the wall thickness is more than 3mm and the diameter is more than 280mm.

The Rockwell and Brinell testing results meet the requirements of the product standards or drawings of most work pieces without conversion. It can take the place of Leeb hardness tester of low accuracy in most cases.
