Internal Micrometer Manual
Product Code : EL-MAILE-10817
Quick Answer: The Internal Micrometer Manual, also known as an inside micrometer, is a precision instrument for measuring the inside dimension of an object, such as the diameter of a hole or the width of a groove, using a micrometer caliper with the points turned outward. It offers a wide range of ID measurements via interchangeable rods, each marked with its own measuring range and adjustable in size with spacing collars, with both the micrometer head and furnished rods satin-chrome finished throughout. It is available in an inch model, accuracy ±(.00024+(.00004xR/2in) where R is the maximum measuring length in inches, and a metric model, accuracy ±(6+L/50)µm where L is the maximum measuring length in mm, with a graduation of 0.01mm or .001″.
