非金属表面粗糙度测量仪，国内外市场尚未见此类专用仪器。我们研制的仪器通过更换三个探测头实现从１级到１４级的测量，对多种形状和大小的工件，都可以测量，消除了系统误差。其检测结果由控制器上的ＬＥＤ数码管显示出来，并可通过打印机打印出来，绘出曲线。既能在实验室测量也能在现场测量。 Non-metallic surface roughness measuring instrument, domestic and foreign markets have not seen such special equipment. The instruments we have developed measure from level 1 to level 14 by changing three probes and can measure and eliminate system errors for workpieces of many shapes and sizes. The test results by the controller LED digital display, and can print out through the printer, draw the curve. Both in the laboratory measurement can also be measured in the field.
