UKAS Calibration Certificates
We offer two levels of calibration certificate for plain plug, screw plug, screw ring and taper screw gauges: a UKAS-accredited certificate, and a Standard Traceable certificate that's traceable to national standards without the UKAS accreditation. Coverage is up to 100mm/4" for plug, ring and taper screw ring gauges, and up to 50mm/2" for taper screw plug gauges.
Turnaround is up to 14 days from when we receive the gauge, one certificate per gauge. Need something outside this range, or a custom certificate? Call the office for a price and lead time.
