NPL has several CMMs suited for different sizes of components (from sub-millimetre to around one metre), which can be programmed to measure a wide range of features ranging from simple dimensions such as lengths, diameters, radii, through form and geometry parameters including flatness, straightness, parallelism, cylindricity, to complex geometry elements such as angular intersections, plane angles, etc. Measurements of artefacts against CAD models or drawings can be undertaken and article inspection reports produced. One CMM is fitted with a laser scanning head, which can be used to rapidly scan an object.

Large object can be measured using seven axis articulated arms, fitted with laser scanners and touch probes. These can rapidly measure an object whilst giving the operator great flexibility to access complex shapes.

Extremely small components (size in the order of tens of millimetres) and those that have small features can be measured on a micro-CMM with sub micrometre accuracy or a variety of unique NPL built instruments, including a metrological AFM.
