In House Calibration
In-House Calibration Service
Precision you can prove.
A dedicated in-house calibration laboratory keeping your gauges and measuring instruments accurate, compliant, and traceable to national standards — without the long lead times of sending them away.
STATUS: IN TOLERANCE
Why it matters
Accuracy isn't optional. It's the foundation.
Regular calibration keeps the readings you depend on trustworthy — on the production line, in the workshop, and through every quality-critical inspection. Our in-house laboratory removes the guesswork, the long lead times, and the uncertainty that come with sending instruments to a third party.
As a gauge specialist, we understand how these instruments are built and how they're used — so we know exactly what good looks like, and we can tell you the moment something drifts out of tolerance.

Thorough, repeatable, easy to manage
Five controlled stages take your equipment from arrival to return — with full documentation at every step.
Receipt & inspection
Every instrument is logged, identified, and visually inspected for damage or wear before any work begins.
Calibration against reference standards
Each gauge is checked against calibrated reference equipment that is itself traceable to national measurement standards.
Adjustment where possible
If an instrument is out of tolerance and adjustable, we bring it back into specification, then re-verify its performance.
Documentation
A full calibration certificate records the results, the standards used, and the measurement uncertainty where applicable.
Return & recall
Your equipment comes back promptly. We can also set up reminders so nothing slips past its calibration due date.
Traceability & standards
An unbroken chain you can present with confidence.
Confidence in a result depends entirely on traceability. Our reference standards are traceable to national measurement standards [via UKAS-accredited sources — insert your route], giving you a documented chain you can stand behind during audits and inspections.
National standards → our reference standards → your instrument → your certificate
Calibration is carried out in line with [ISO 9001 / ISO/IEC 17025 — insert the standards that apply to your lab], so the certificates we issue stand up to your customers and regulators.
