As our laboratories are COFRAC accredited (2-1218), we deliver COFRAC certificates of calibration covering the basic reporting of conventional mass correction, uncertainty and traceability information. Our certificates are available in various languages (bilingual English, German, Spanish, Italian or Portuguese).

We insure verification, repair and calibration for weights and masses – regardless of their origin.

ZWIEBEL is also there to assist you in defining, studying and producing your specific weights and masses.
