MRR(M)-150D1型液晶屏数显洛氏-表面洛氏硬度计外观新颖，界面菜单化，测量装置采用光栅传感器及计算机控制，硬度示值在液晶屏上直接显示是机电一体化的硬度测试仪器。该机能进行各种硬度参数相互自动换算，鉴别试件ZUI小厚度参数相互自动换算，鉴别试件ZUI小厚度和测定试验的环境温度。内置打印机，读取相关试验结果。实现了自动化操作，消除人为操作和读数误差。
该硬度计适用于硬质合金、炭化物、表面淬火钢、硬化薄板、淬火钢、调质钢、冷硬铸铁、铸铁、铝、钢、镁等合金钢。
MRR（M）-150D1 type lcd holds the number shows the rockwell surnamerockwell degree of hardness accounts the external appearance novel,the interface menu turns,measuring equip to adopt the light grid spreads tofeel machine and calculators control,the degress of hardness shows the value to hold in the lcd the direct manifestation in top is a degree of hardness test instrument thag machine electricity integral whole turn,the function,sproceeding every kind of degree of hardness parameter converts automatically mutually,distcriminating to try an environment for the minimum thickness experiments with the measurement temperature.the inside places the printer,reading related experimenting the result.realizes the automation operates,dissolving the factitiousness operate with read the few error margin.
That degress of hardness accounts to be applicable to the hard metals,carburizing steels,quenching steels,hardcast irons,mild steels,Al,Cu and malleable irons.
