R(D)-45D1型電動表面洛氏硬度計具有性能穩(wěn)定,結(jié)構(gòu)牢靠、**，操作方便等特點(diǎn)。采用自動加卸試驗力方法，保荷時間穩(wěn)定，消除了人為操作誤差，示值精度高。
該硬度計適用硬質(zhì)合金、滲碳鋼、淬火鋼、硬鑄鐵及軟鋼、鋁合金、銅合金和可鍛鑄鐵的硬度的測定。
This tester is a popular type rockwell hardness testing machine,the construction is firm and reliable and safe,operating convenience etc.characteristics.The adoption adds to unload automatically to experiment the dint method,protecting time of stable,dissolves artificial operation error margin,show the worth accuracy high.
That degree of hardness accounts to be applicable to the black metals and have the rockwell surname degree of hardness measurement of the color metals.It is extensive to be applocable to factory car with calculate the section.
