. Automatic hardness test, LCD digital display
. Hardness conversion between Rockwell and Brinell hardness scales
. Precision conforms to GB/T 230.2, ISO 6508-2 and ASTM E18
This equipment may be used to determine the Rockwell hardness of steel bottle after heat treatment. It can remove the oxidation-layer on the surface of workpiece, finish the steps of loading, dwelling and unloading, and digitally display the Rockwell hardness number. Above processes are all automatic. The measured Rockwell hardness can also be converted to Brinell hardness number. The specially designed software can be used for storage, statistic, edit, analysis of the testing data.
Measuring range: 20-88HRA, 20-100HRB, 20-70HRC
Preliminary test force: 9.807N (10kgf)
Total test force: 588.4, 980.7, 1471N (60, 100, 150kgf)
Hardness resolution: 0.1HR
Testing speed: ≤120 seconds/point (from clamping started to clamping released)
Power supply: 220/380V, 50Hz
According to customer's request, we can also supply this machine with Large-flat test bench (as same as the one of HBM-3000B) instead of carrying wheel as the following picture. In this case, it will not be an on-line machine.
