UKAS Calibration Service

Opus has one of the largest (162m²), best equipped UKAS Accredited Calibration Laboratories in the UK.
It is temperature controlled at 20° ±1°C and locally for some specialised measurements at ± 0.5°C.

Opus offers two types of service:
• A Laboratory-based Calibration service at Corby for portable measuring instruments.
• An On-Site Calibration service for larger instruments including Surface Plates,Surface Tables, Profile Projectors and other large items.

Additionally, to avoid being without instruments for extended periods of time, we also offer a “Pre Booking Service” for both Laboratory based and On-Site Calibration which reserves a calibration slot in our schedule.

Please contact us for further details of our “Pre-Booking Service”
