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 of error, the smaller the uncertainty will be. In other words, when repeating a "calibration chain" to "ensure traceability," the more calibration instances there are, the greater the uncertainty becomes, and the lower the reliability. This is because environmental factors, the inherent errors of the instruments, and errors introduced by the measurer 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 instruments that are as close as possible to national standards. At Tekune Measurement, we possess and sell instruments that are close to national standards. For more details on uncertainty and traceability, please visit the URL below.
