内径百分表

1.用于测量内径尺寸   For internal measurement.
2.带可换测头，测量范围大   Changeable anvils for wide measuring ranges.
3.配φ57mm普通表圈百分表   Equipped with a φ57mm dial indicator.
4.带两个测量头架，分别测量φ20-φ50mm，φ50-φ200mm   With two measuring head frames, the measurement range is respectively φ20-φ50mm and φ50-φ200mm.
5.带两种接杆可测量不同的深度内孔、测控深度范围为24-300mm（从隔热套以下开始计算）   With two kinds of connecting rods to measure the internal holes of different depths range of measuring holes is 24-300mm(starting from below heat shield).
