The relationship between uncertainty and traceability.
Possessing and selling equipment close to national standards to ensure traceability!
Uncertainty is like the sum of factors contributing to error, so naturally, the fewer the factors contributing to error, the smaller the uncertainty will be. In other words, when repeating a "chain of calibrations" to "ensure traceability," the more calibration instances there are, the greater the uncertainty and the lower the reliability. This is because environmental factors, equipment errors, and measurement errors accumulate with each calibration. Generally, it is said that adding one more calibration doubles the uncertainty. Therefore, even when calibrating to ensure traceability, it is better to perform the calibration with equipment as close to national standards as possible. At Tekune Measurement, we possess and sell equipment that is close to national standards. For more details on uncertainty and traceability, please visit the URL below.
