Magnetic Portable Hardness Tester


Based on the fact that it is impossible to conduct on-site Rockwell and Brinell hardness testing on large steel plates, steel pipes, shafts, molds, boilers, pressure vessels and pressure pipelines, Shenyang TX independently developed a magnetic portable hardness tester.


Shenyang TX's magnetic portable hardness tester can be divided into PHBR-200 digital display magnetic Brinell hardness tester,  PHBR-100 magnetic Brinell hardness tester, PHB-200 magnetic Brinell hardness tester, PHR-200 magnetic Rockwell hardness tester and PHR-100 magnetic Rockwell hardness tester. Among them, the magnetic portable hardness tester of digital display series adopts high-precision force sensor and unique displacement measurement. For the part of Rockwell hardness testing, it simplifies the operation of Rockwell hardness test. As long as the total test force is directly applied and all test forces are directly unloaded after maintaining the test force, Rockwell hardness measurement can be completed. This design can complete Rockwell hardness measurement of the measured workpiece within 10 seconds, The production efficiency is greatly improved. For Brinell hardness testing, this instrument provides two Brinell hardness testing methods. The first is the traditional Brinell hardness testing method, that is, select the appropriate indenter and test force, press out the Brinell indentation on the surface of the measured workpiece, and calculate the Brinell hardness value after the indentation diameter is measured by the optical system. The second is the Brinell hardness test by sounding method, which is clearly specified in the American Standard ASTM E103. It is a fast Brinell hardness test method that can directly read out the Brinell hardness value. The specific operation method is to collect a series of standard hardness blocks that are the same as the material of the workpiece to be tested before batch testing of the workpiece, and make the hardness curve of this material. Then PHBR-200 or PHB-200 can be used for rapid Brinell hardness testing of the workpiece. This Brinell hardness testing method is especially suitable for Brinell hardness testing of the same batch of workpieces one by one.


Shenyang TX's magnetic Series Portable Hardness Tester weighs only about 5kg. As long as it can be adsorbed to the surface of the tested part, the test can be completed by contacting the part on one side. It is especially suitable for on-site Brinell and Rockwell hardness testing of large and medium-sized workpieces in industrial production site.
