Weights and masses in compliance with OIML R111

ZWIEBEL, the leading French manufacturer of precision weights and masses that comply with the international R111-2004 recommendation of the OIML (International Organisation for Legal Metrology). Our weights and masses are made out of stainless steel, brass or cast iron.

ZWIEBEL is able to meet all types of requests, from 0.1mg to 2 tonnes, for all classes (E0, E1, E2, F1, F2, M1, M1-2, M2, M2-3, M3). According to the OIML R111 recommendation and depending on their class, our weights and masses are available in monoblock or with an adjusting cavity.

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.

Our experience enables us to propose any type of material, shape and composition, finish, tolerance, identification and customization of special weights. We can also provide accessories and packaging for our products.
