In-depth technical articles on instrumentation, measurement uncertainty, NABL/ISO 17025, and laboratory best practices — written by practitioners.
Calibration and verification are not the same thing. Calibration determines the measurement performance of an instrument by comparison with a suitable reference standard, while verification checks whether the instrument meets specified requirements or acceptance criteria. Learn the practical difference between calibration, verification and adjustment, with examples, error calculations, uncertainty and conformity decisions.
What is calibration and why is it important? Calibration is the technical comparison of a measuring instrument against a suitable reference standard to determine its measurement performance. Learn the difference between calibration and adjustment, understand error, correction, uncertainty and traceability, and discover why regular calibration is essential for reliable measurements in industrial and laboratory applications.
Stability in a temperature source shows how steady the temperature remains with time at a fixed location after the set temperature is reached. In calibration, good stability is essential because it improves repeatability, reduces measurement uncertainty, and supports reliable comparison between the reference standard and the instrument under calibration. This article explains stability in simple language with examples, calculation method, common causes of poor stability, and practical ways to improve it.
Calibration is the process of comparing a measuring instrument with a known reference standard to check its accuracy. It helps identify error, apply correction where required, maintain reliable measurements, support audits, and build confidence in quality decisions.
