內徑百分表

1.用于測量內徑尺寸   For internal measurement.
2.帶可換測頭，測量范圍大   Changeable anvils for wide measuring ranges.
3.配φ57mm普通表圈百分表   Equipped with a φ57mm dial indicator.
4.帶兩個測量頭架，分別測量φ20-φ50mm，φ50-φ200mm   With two measuring head frames, the measurement range is respectively φ20-φ50mm and φ50-φ200mm.
5.帶兩種接桿可測量不同的深度內孔、測控深度范圍為24-300mm（從隔熱套以下開始計算）   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).
