标准配置
    当前测试硬度可采用的方法有多种, 比较常见的有布氏、洛氏、维氏、里氏等试验法。其中布氏、洛氏试验力大、压痕大,对被试样表面损伤较大,维氏采用光学法进行测量,需非常专业的技术人员操作,并且不能对大型工件进行直接测试,而超声波硬度计采用超声波接触阻抗法对试样进行比较测量,具有精度高、速度快、易便携、操作简单,无损测量等优点
    ● 测量精度高——可达±3%HV,±3%HB,±1.5HR。(此测量精度在使用测试支架情况下测得)
    ● 测试压痕小——需要用高倍显微镜才能观察到。
    ● 测量速度快——可在2秒内输出测试结果。
    ● 大屏幕显示——直接显示当前测量值,累计测量值,最大值,最小值,平均值及单位转换值。
    ● 海量存储——可在仪器内存储2000组测量数据。
    ● 校正简单——可在仪器内存储20组校正数据,1组默认数据,用户可设置19组。
    应用范围
    ● 法兰盘边缘和齿轮根部冲压件、工模、薄板、表面硬化的齿和齿轮槽、锥度部分的硬度测量;
    ● 轴和薄壁管道、容器的硬度测量;
