Metrology & Quality Services


Jk Metrology & Quality Services of Liskeard Cornwall was taken over by William Hughes in May of this year. All processes and services are moving to a new laboratory at William Hughes’ head office in Stalbridge, Dorset. John Kelly, the JK in JK Metrology and ex-head of UKAS Laboritories, is still very much a part of the operation. His depth of experience and wealth of knowledge will be a valuable asset to the successful integration of the business.

Our services

We are able to offer metrology, and quality consultancy for ISO 17027, ISO 9000 etc. in addition to a UKAS calibration service to ISO 17025. Additional investment by William Hughes in resources and people will provide a range of benefits, not least a reduced turnaround time, for this long-established and well-respected business.

With a worldwide portfolio of customers already on board, William Hughes has now become one of only 3 UK laboratories offering UKAS Calibration of Gauge Blocks by Inferometry (Class A) together with “By Comparison” calibration.

Interferometry is the highest level of accuracy for length measurement and William Hughes can also measure items up to 1 metre long at 20°C ± 0.05ºC.
