Modern micrometer with a reading of 1.639 ± 0.005 mm. Assuming no zero error, this is also the measurement. (One may need to enlarge the image to read it.) Outside, inside, and depth micrometers. The outside micrometer has a unit conversion chart between fractional and decimal inch measurements etched onto the frame
The technicians who work in the PMEL will often specialize in one of these sections. The K-Sections are derived from the primary function of the TMDE. This is based upon the calibration authority. Most labs have three calibration sections divided into K1/K8, K5/K6 and K3/K4 that specialize in like test equipment.
Snap go/no go gauge and indicator snap gauge. A snap gauge is a form of go/no go gauge.It is a limit gauge with permanently or temporarily fixed measurement aperture(s) (gaps) which is used to quickly verify whether an outside dimension of a part matches a preset dimension or falls within predefined tolerances.
Gauge blocks are a common method for precise measurement or calibration of measurement tools. For small or microscopic objects, microphotography where the length is calibrated using a graticule can be used. A graticule is a piece that has lines for precise lengths etched into it.
A pair of go and no-go gauges. A go/no-go gauge is an inspection tool used to check a workpiece against its allowed tolerances via a go/no-go test. Its name is derived from two tests: the check involves the workpiece having to pass one test (go) and fail the other (no-go).

Two inside calipers. Inside calipers are used to measure the internal size of an object. The upper caliper in the image (on the right) requires manual adjustment prior to fitting. Fine setting of this caliper type is performed by tapping the caliper legs lightly on a handy surface until they will almost pass over the object.
ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories is the main standard used by testing and calibration laboratories. In most countries, ISO/IEC 17025 is the standard for which most labs must hold accreditation in order to be deemed technically competent.
