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.
Understand the difference between stability and uniformity in temperature sources such as dry blocks, liquid baths, ovens, and chambers. This article explains how stability shows temperature consistency over time, while uniformity shows temperature distribution across different locations, and why both are essential for reliable calibration results.
