Metrology & Calibration

Metrology is essential to guarantee the reliability of results delivered by a measuring instrument throughout its lifecycle. It involves regular verification, inspection, and calibration of instruments to ensure measurement accuracy, operational safety, and alignment with industrial requirements. At Sefelec, our customers operate high‑precision measuring instruments and must regularly confirm that they still measure correctly. Therefore, we recommend annual calibration, with frequency adjustable based on usage intensity and production requirements. Why is metrology essential? Maintain measurement accuracy Any measuring instrument may drift over time. Metrology allows us to detect and correct deviations, ensuring precise measurements and production quality. Ensure compliance with standards Equipment must meet technical reference standards. Calibration using a reference standard verifies and validates compliance and ensures metrological traceability. Secure your industrial processes Incorrect measurements can cause non‑conformities, manufacturing defects, or risks related to electrical installations. Metrology helps reinforce safety and productivity. Adapt calibration intervals to your activity Although one year is recommended, each customer may choose their own schedule based on: production volume required quality level instrument usage intensity What is included in a “calibration” service? Calibration is a rigorous process consisting of comparing the instrument with a reference standard (a highly precise instrument). We verify any deviation between the two, then adjust the instrument if necessary. In short, calibration verifies and corrects a measuring instrument. What is the difference between Calibration and Metrology? Metrology encompasses all rules and methods guaranteeing measurement reliability, whereas calibration is a specific step: comparing an instrument to a standard to verify or adjust its precision.
