HRD-45 electric surface Rockwell electronic hardness tester

HRD-45 electric surface Rockwell electronic hardness tester

HRD-45 electric surface Rockwell hardness tester is based on the ordinary surface Rockwell hardness tester, using the motor automatic control test force loading, holding, unloading process, can choose the load holding time, simple and rapid operation, except the dial to zero, there is no artificial error, with high sensitivity and stability.


Feature & Use:


HRD-45 electric surface Rockwell electronic hardness tester is based on the ordinary surface Rockwell hardness tester, using the motor automatic control test force loading, holding, unloading process, can choose the load holding time, simple and rapid operation, except the dial to zero, there is no artificial error, with high sensitivity and stability;
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 dial is directly read the hardness value, and can be matched with other scales of Rockwell.
By using lever less load, the friction free spindle is adopted, and the test precision is high.
By controlling the loading, loading and unloading of test force by motor, the manual operation error of manual Rockwell is eliminated.
Accuracy is in line with GB/T230.2, ISO6508-2 and American ASTM E18 standard.
●Application area:
1. Surface hardened steel, copper, aluminum alloy sheet, strip steel, hard alloy steel;
2, galvanized, chrome plated, tin plated, material surface heat treatment and chemical surface treatment of various metal materials.
