JDY-4高測(cè)長(zhǎng)儀的詳細(xì)信息

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

特點(diǎn)：用計(jì)量光柵作儀器長(zhǎng)度基準(zhǔn)，長(zhǎng)度基準(zhǔn)溯源性好，高；用機(jī)動(dòng)，自動(dòng)代替手動(dòng)操作，使儀器測(cè)量穩(wěn)定可靠。按"實(shí)時(shí)綜合修正"方法，用計(jì)算機(jī)軟件對(duì)儀器測(cè)量誤差實(shí)行總體性的一并修正。測(cè)量結(jié)果即能數(shù)字顯示，又能自動(dòng)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.
