How the Calibration Process Works
Every calibration we carry out in Coventry is performed entirely on your premises, following a rigorous and structured process:
Environmental Assessment:
Before testing begins, our engineer evaluates the conditions at your site — checking surface stability, temperature, vibration, and any environmental factors that could affect accuracy. Calibrating equipment in the environment where it actually operates gives a far more meaningful result than a laboratory bench test.
Reference Testing & Comparison:
A certified reference weight — fully traceable to national standards — is applied across multiple test points on each scale. This includes corner load tests to detect uneven weight distribution, repeatability tests to confirm consistent readings, and full-capacity linearity checks from zero to maximum load.
Error Identification & Adjustment:
Where any discrepancy is found between the scale's output and the reference weight, our engineer performs on-site adjustments to bring the equipment back within required tolerances. In most cases this is completed within the same visit — no waiting, no sending equipment away.
Certification:
A formal calibration certificate is issued digitally at the point of service, detailing the equipment tested, reference weights used, results recorded, and pass/fail status. This provides the traceable documentation your auditors, quality managers, and regulatory bodies require.
For equipment requiring more significant repair, our engineers carry out on-site assessments and can arrange follow-up visits or, in many cases, complete mechanical repairs during the same call.
Why Coventry Businesses Choose Oakleyweigh
Audit Readiness, Every Visit
We maintain a full asset register of your weighing equipment, calibration history, and service schedule, sending reminders when your Coventry site is due for its next visit. Digital certificates are issued same-day in a format accepted by BRC, ISO 9001, HACCP, and UKWF auditors — so when an inspection arrives, you're already prepared.
Specialised Industry Support
Coventry's industrial mix demands broad expertise. We calibrate everything from precision laboratory balances in pharmaceutical and research settings to heavy-duty floor scales and pallet weighers in distribution and automotive supply chain facilities. Our engineers also service the full range of medical and healthcare scales for NHS trusts, care homes, and private clinics across Coventry and Warwickshire.
Flexible Service Agreements
We offer both rolling maintenance contracts and one-off visits. For businesses with multiple scales across several Coventry or Warwickshire sites, a managed service contract ensures nothing falls overdue and your calibration records stay consistently clean.
Comprehensive Services for Coventry and Warwickshire
- On-Site Calibration: Our mobile engineers visit your Coventry premises and carry out the full calibration process in situ, in accordance with the UKWF Code of Practice. No transport risk, no couriers, minimal disruption. We cover all CV postcodes and the wider Warwickshire region.

- Specialist Equipment: We calibrate the full range — from laboratory balances accurate to 0.001mg used in Coventry's pharmaceutical and research facilities, through to industrial floor scales rated up to 2,000kg in warehousing and automotive supply chain operations.
- Medical Scale Servicing: Supporting University Hospitals Coventry and Warwickshire NHS Trust, GP surgeries, care homes, and private clinics across the region. We service hoist scales, chair weighers, infant scales, and bed weighers, with certificates appropriate for CQC and healthcare audit requirements.
- Emergency Breakdown Cover: A failed scale before an audit or mid-production cannot wait. Our Coventry-area engineers offer rapid response call-out — contact us to discuss your timeline and we'll aim to have an engineer with you the same day or next morning.
- Maintenance Contracts: For businesses with multiple units or frequent calibration requirements, a rolling service agreement keeps your equipment in tolerance, your records current, and your compliance obligations met without having to manage the schedule yourself.
