測長儀|JDY-2
本儀器主要用于各種圓柱形、球形、平行平面等精密零件的外形,內(nèi)孔尺寸的直接測量和比較測量,亦可進(jìn)行內(nèi)外螺紋中徑等特殊測量,是各級(jí)計(jì)量室中的基本長度計(jì)量儀器之一。
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.
