DescriptionThe Mitutoyo HT-3"R Holtest Vernier Inside Micrometer is a precise, three-point analog instrument used for measuring the internal diameters of bores. The "R" in the model name indicates that it has a ratchet stop, which provides a constant measuring force for repeatable results. The three measuring anvils are positioned 120° apart to enable self-centering within the bore and to ensure accurate readings. |
