    R（M）-45D1型液晶屏數(shù)顯表面洛氏硬度計(jì)以新穎的外觀，直觀的液晶屏顯示裝置和單片機(jī)控制系統(tǒng)，使表面洛氏硬度測(cè)試實(shí)現(xiàn)了自動(dòng)化的操作。除試臺(tái)手動(dòng)升降外，完全實(shí)現(xiàn)了試驗(yàn)力的施加、卸除、硬度值直接顯示等自動(dòng)化運(yùn)作，本機(jī)測(cè)試精度高，消除了人為操作誤差，是一臺(tái)機(jī)電一體化高科技先進(jìn)的硬度測(cè)試儀器。
    該硬度計(jì)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(cè)定。

    Digital LCD display Superficial Rockwell Hardness Tester is a popular type rockwell hardness testing machine,the construction is firmand reliable and safe,intuitive screen display devices and SCM control system so that the surface of Rockwell hardness testing to achieve the automation of operations. In addition to Anvil manual movements, the full realization of the imposition of a test,removable,hardness, and other automated operation showed that direct, high accuracy of this test, to eliminate the human error of operation, is a high-tech electromechanical integration of advanced hardness Testing equipment. 
    That degree of hardness accounts to be applicable to the black metals and have the rock well surname degree of hardness measurement of the color metals.It is extensive to be applocable to factory car with calculate the section.
