SRBR-200 Magnetic Digital Brinell and Rockwell Hardness Tester are designed on the basis of SRRH-200 Magnetic Digital Rockwell Hardness Tester; it has the same appearance and mechanical structure as SRRH-200, which can make accurate Brinell hardness test with conventional indentation method of ISO 6506.2 and ASTM E10. it can also make rapid Brinell hardness test with depth-measuring method of ASTM E103, and read hardness value directly. At the same time it also can do Rockwell hardness test according to Rockwell hardness testing method in ISO 6508.2 and ASTM E18. These functions can meet the demand of precise and rapid Brinell hardness testing on-site of large steel and iron parts. Simplified operation of Rockwell hardness and depth-measuring Brinell hardness very simple with high efficiency.
This instrument stores an accurate basic hardness, that is depth curve made from plenty hardness blocks. It also stores several Brinell curves of common materials. We can supply the service of making precise Brinell curve of common material according to customers' requirement. Advanced curve correction methods can be used to test a variety of special material. This instrument can check and calibrate the accuracy on-site by precise indentation method at any time.
Only if there is suitable surface, it could test those too large or heavy iron and steel workpieces whereas the desk tester could not. It could test the hardness of steel plates, steel pipes, profile steel, bearings, moulds; boilers, pressure vessels, and weld bead on pressure pipes; castings, forge pieces and large and medium-sized heating parts with available surface.It is suitable for testing a large batch of parts piece by piece on site. In a wide range of manufacture industry, it could replace Leeb hardness tester which is not accurate or reliable enough.
