HR-45A Rockwell surface metal hardness tester

HR-45A Rockwell surface metal hardness tester

The HR-45A surface Rockwell hardness tester is one of the Rockwell hardness tester, using smaller test force to test the fine, small, thin specimens that ordinary Rockwell hardness tester cannot test, as well as the workpiece with the surface hardening layer and the workpiece requiring the smallest indentation. 

Feature & Use:

The HR-45A Rockwell surface metal hardness tester  is one of the Rockwell hardness tester, using smaller test force to test the fine, small, thin specimens that ordinary Rockwell hardness tester cannot test, as well as the workpiece with the surface hardening layer and the workpiece requiring the smallest indentation. ;

The product fuselage part is molded by casting process once and has been treated for a long time. Compared with the technology of plate splicing, long-term use of variable shape is very small, and it can effectively adapt to all kinds of harsh environments.
Automotive paint, high quality paint, strong scratch resistance, use for many years is still bright as new;
The test force is small and the indentation is small, which does not affect the continuous use of the specimen.
The manual Rockwell hardness tester is accurate, reliable, durable and highly efficient.
Dial direct reading, HRN, HRT, and can be matched with other scales of table Luo.
By using lever less load, the friction free spindle is adopted, and the test precision is high.
Adopting a precision hydraulic buffer made of one-piece casting without leakage of buffer, and unloading smoothly and without impact, and adjustable speed.
Accuracy is in line with GB/T230.2, ISO6508-2 and American ASTM E18 standard.
●Application area:
Surface quenched steel, copper, aluminum alloy sheet, strip, hard alloy steel, galvanized, chrome plating, tin, surface heat treatment and chemical surface treatment of all kinds of metal materials.
