Eley Metrology & Crown Windley
Since 1976, Eley Metrology has established itself as a leading designer, manufacturer, and supplier of some of the most accurate measuring machines, artefacts, and foundations in metrology.

As one of the UK’s longest-serving private manufacturers, with more than 120 years of combined heritage between Eley Metrology and Crown Windley, the company is recognised as a key innovator and solutions specialist in the metrology space.

Eley Metrology delivers an extensive range of products and services. Starting with foundations, Eley granite surface plates and tables are available in both standard and bespoke sizes. They are proven to be a long-term investment, representing the highest quality available, and feature some of the UK market's most robust and thickest granite (for larger sizes), hand-lapped to BS 817:2008 specifications. Eley Metrology pairs these products with on-site maintenance services, helping ensure equipment remains traceable and within specification.
Their bespoke capabilities are unrivalled, with options available across their full product range.
Eley’s Coordinate Measuring Machines (CMMs) rank among the most accurate available, benefiting from a non-error-mapped design. Designed and certified at their Derby headquarters, Eley was the first CMM manufacturer worldwide to achieve ISO 10360 certification, with every machine calibrated in their UKAS-accredited laboratory to ISO 10360-2.
The company’s success is built on its ability to solve precision measurement challenges that others cannot. This is supported by their vertically integrated manufacturing approach, keeping many stages of production under one roof. This commitment to consistency and quality is evident throughout their product and service offering.
Eley's range includes near-frictionless Vertex VMS digital height gauges and the Long Bore Measurement Machine, used for measuring tubular precision components. Both exemplify Eley's innovation, offering unique capabilities unmatched in today's measurement industry.
Through a tailored approach, Eley Metrology provides comprehensive solutions to the aerospace, automotive, defence, rail, nuclear, and precision engineering sectors, among others.
Eley Metrology solves measurement challenges with reliable, trusted service.
