Calibration
Now an Official DeFelsko Authorised Service Centre
Accurate readings are the foundation of reliable inspections. That’s why regular calibration is essential for every coating thickness gauge and inspection instrument.
At DFT Instruments, we provide professional calibration services carried out in the UK. As a certified DeFelsko Authorised Service Centre (DASC), our technicians follow factory-approved procedures using genuine parts, certified tools, and traceable standards. The result? Total confidence that your gauge performs exactly as it should.
Why Calibration Matters
Calibration is more than just a box-ticking exercise — it’s the assurance that every reading you take is accurate, repeatable, and trusted. Over time, even the most robust gauges can drift due to regular wear, environmental conditions, or simple day-to-day use. Without routine calibration, you risk decisions being made on unreliable data.
-
Maintain Accuracy Over Time – Paint thickness gauges and inspection instruments are exposed to tough job-site conditions. Regular calibration ensures they continue to provide precise measurements, even after years of service.
-
Ensure Compliance – Many industries, from aerospace to construction, demand documented evidence that instruments are within tolerance. Regular calibration helps you meet ISO, ASTM, and other quality-assurance standards.
-
Traceable Confidence – A calibration certificate traceable to recognised standards (UKAS, NIST, or PTB) provides documented proof of accuracy — vital for audits, contracts, and regulatory compliance.
-
Reduce Risk & Costly Errors – An uncalibrated gauge could lead to coatings being too thin or too thick, causing failures, rework, or costly warranty claims. Calibration protects both your reputation and your bottom line.
-
Peace of Mind for Inspectors – When working on high-value assets like bridges, ships, or aircraft components, knowing your instrument is factory-approved accurate gives you the confidence to stand by your results.
At DFT Instruments, we believe calibration is not just a maintenance step — it’s an investment in quality, compliance, and long-term reliability.
Calibration Services
At DFT Instruments, we don’t just check your gauge — we provide a comprehensive service programme designed to keep your equipment working like new. Whether you need a quick recalibration, a repair, or long-term support, our services ensure your instruments deliver accuracy, reliability, and value for years to come.
-
Routine Recalibration – Instruments naturally drift over time, so scheduled recalibration ensures your results remain consistent and trustworthy. Our process restores your gauge to factory-level accuracy.
-
Certificate of Calibration – Every recalibrated or serviced instrument is returned with a long-form certificate traceable to UKAS, NIST, or PTB standards. This documented proof of accuracy is included at no extra cost (typically a $95–$250 USD value when purchased separately).
-
Repair & Diagnostics – If your gauge develops a fault, our technicians carry out a full assessment and repair using genuine DeFelsko parts, backed by factory-approved methods.
-
Preventative Maintenance – Don’t wait for an instrument to fail. We offer proactive maintenance to help avoid costly downtime and extend service life.
-
Upgrades & Firmware Support – Keep your equipment fully up to date with the latest DeFelsko firmware and features, ensuring compatibility and maximum performance.
-
Instrument Care Advice – Our team provides guidance on handling, cleaning, and storage to help you protect your investment long-term.
