Cleaning & calibration ships with a Certification of Quality.
A certified cleaning and calibration comes back with a signed Certification of Quality — your formal report and proof of service. It declares the unit meets or exceeds its original design and test parameters, and documents the standards and functional checks behind that result. A repair-only job is different: if you simply need the instrument diagnosed and running again, that's exactly what we do — no calibration certificate is issued.
- Calibration traceability
- NIST-traceable standards
- Electromagnetic compatibility
- EMC Directive 89/336/EEC
