Magnetic Rockwell Hardness Tester
Features of Magnetic Rockwell Hardness Tester
1. The magnetic Rockwell hardness tester has its testing head fixed onto the surface of steel workpieces through a magnetic absorbing disc, and accomplishes testing upon single side touch, with no need of sampling, removing or supporting the workpiece.2. Working on practicable Rockwell hardness testing principle, the magnetic hardness tester has high testing precision, in compliance with ISO6508.2 standard. Also, its test error is no more than 1.5HRC tested, by the National Institute of Metrology.
3. It is fast, convenient, and of no damage.
4. A drum reading device is utilized for convenient reading, high repeatability and precision.
5. The magnetic Rockwell hardness tester is equipped with a magnifier with lamp, so that you can see the distinct reading in the darkness of the workshop.
6. The magnetic hardness tester is extensively applicable to the hardness measurement of flat components, curved components with the diameter more than 50mm, large workpieces, assembled parts, non-slicing and not easily movable parts.
7. It can also be used for on site precision hardness testing for steel plate, steel tubes, axles, moulds, large forgings, and a variety of large and medium-sized heat treated parts.
8. The magnetic Rockwell hardness tester is adopted to test the hardness of welding seam, heat-affected zone and parent metal in the finished pressure vessels.
9. The PHR-100X hardness tester is applied to striped parts like small machine tool guide way.
10. During production inspection and acceptance inspection, the magnetic Rockwell hardness tester is used in place of Leeb hardness tester.
11. Traceable standard hardness block, and qualified indenter examined by standard Rockwell hardness tester.
12. The dynamometer, used to calibrate load, is traceable to the national secondary standards.
