Traceability & Uncertainty Analysis
All PDI instruments and standards under its scope are traceable to the National Institute of Standard Technology by qualified providers. We deliver traceable calibration and inspection which meet all international standards.
Uncertainty studies and calculations were performed on all PDI instruments under its scope. Test methodologies are well recognized and specify limits to the values of sources of uncertainty of measurement. All measurements are supported by uncertainty budgets and are represented as expanded uncertainties using a coverage factor of K=2 at 95% confidence level.
All uncertainty budgets and formulas were calculated with Ian Tobasco, Ph.D. Mathematics, New York University.
