JDY-4高測長儀的詳細(xì)信息

微機進行數(shù)據(jù)處理，光、機、電緊密結(jié)合，能進行內(nèi)外尺寸精密直接測量的臥式高測長儀。主要用于對平行平面狀、圓柱狀、球狀類精密量具和零件的外形、內(nèi)孔、尺寸的測量。利用各種隨機附件，亦可進行內(nèi)外螺紋中徑等多種特殊測量。

特點：用計量光柵作儀器長度基準(zhǔn)，長度基準(zhǔn)溯源性好，高；用機動，自動代替手動操作，使儀器測量穩(wěn)定可靠。按"實時綜合修正"方法，用計算機軟件對儀器測量誤差實行總體性的一并修正。測量結(jié)果即能數(shù)字顯示，又能自動打印記錄。

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.
