JDY-4高测长仪

JDY-4高测长仪的详细信息

微机进行数据处理，光、机、电紧密结合，能进行内外尺寸精密直接测量的卧式高测长仪。主要用于对平行平面状、圆柱状、球状类精密量具和零件的外形、内孔、尺寸的测量。利用各种随机附件，亦可进行内外螺纹中径等多种特殊测量。

特点：用计量光栅作仪器长度基准，长度基准溯源性好，高；用机动，自动代替手动操作，使仪器测量稳定可靠。按"实时综合修正"方法，用计算机软件对仪器测量误差实行总体性的一并修正。测量结果即能数字显示，又能自动打印记录。

It is one of the basic length-measuring instruments for metrological departments. It is applicable for both direct and comparative measurements of outer and inner dimensions of workpieces such as parallel planes, spheres, cylinders and bores. By using various accessories, it can be used for special measurements, such as pitches of male threads and female threads.
