Measure the internal dimensions of an object with this micrometer from the trusted RS PRO series. Commonly found in the construction industry, an internal micrometre measures the inner diameter of a hole.

Available with six extensions to allow for readings between 50 mm to 600 mm, this micrometer is accurate to measurements of 0.01 mm. The barrel and sleeve are scratch-resistant and readings won't be obscured due to light reflections thanks to the anti-glare satin chrome material. Each set contains a micrometer head with a locking screw, so you can lock extensions in place to achieve the most precise measurements.

An internal micrometer is suitable for measuring the inside dimensions of hollow objects such as pipes or bearings. For safety and easy portability on-site, the micrometer and attachments come in a handy rigid case.
