The Precise - 50 to 250 mm, 0.01 mm Tubular Inside Micrometers are pen-like structures that measure an object's inside or inside diameter. The 50 to 250 mm, 0.01 mm Inside Micrometers features a thimble in the middle that turns. Upon turning the thimble, the Micrometers expand exactly as a curtain rod does. Thus, the Tubular Inside Micrometers are ideal for measuring but only when the correct amount of force is applied in turning the ratchet and thimble. The measuring range of the Tubular Inside Micrometers varies from 50 to 250 mm, while its least count is 0.01mm.
