Definition. What traceable calibration means and why it matters for auditors.
Traceable calibration means: The measurement reference can be tracked back without gaps to national standards — in Germany the Physikalisch-Technische Bundesanstalt (PTB).
At Döscher, we calibrate against traceable references. Every delivered sensor receives a calibration protocol with traceability chain.
Important for ISO 9001 audits, IFS Food, FSSC 22000, and all process-relevant audits in food and chemical industries.
FAQ
How often to re-calibrate? +
Recommendation: factory calibration once a year. On-site offset on material change is often sufficient.
Practical tip
Need concrete help for your line?
Three data points — material, temperature, position — are enough for a first sensor recommendation.
