Test weights

We supply test weights and weight sets to meet customers' unique weighing needs. We can supply them in various sizes, shapes or material, marking, adjusted to any tolerance, class (E0, E1, E2, F1, F2, M1, M1-2, M2, M2-3, M3)required. 

We carry test weights from ZWIEBEL, a leading French manufacturer of precision weights and masses that comply with the international R111-2004 recommendation of the OIML, which has been accredited by the French Accreditation Committee (COFRAC)since 1991. 

We can supply COFRACcertificates of calibration covering the basic reporting of conventional mass correction, uncertainty andtraceability information.Alternatively,We can also provide in-house Calibration Certificate.
* COFRAC calibration certificates are recognized in all countries signing the EA agreement (European Cooperation for Accreditation).

Scientific range of weights and masses in classes E, F and M OIML WEIGHTS FROM 1mg to 50kg E0, E1 and E2 classes These weights, except E0 class, are according to the international OIML R111 recommendation in terms of material (roughness, magnetism,...) and shape and marking. Class E1 weights are intended to ensure traceability between national mass standards and weights of a lower accuracy class. Class E2 weights are intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of special accuracy class I. Class E2 weights or weight sets have to be accompanied by a calibration certificate. OIML WEIGHTS FROM 1mg to 50kg F1 and F2 classes These weights are according to the international OIML R111. Weights intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of special accuracy class I and high accuracy class II. They can also be used as control weights and are usually accompanied by a calibration certificate. OIML WEIGHTS FROM 1mg to 50kg M1, M2 and M3 classes These weights are according to the international OIML R111. Weights intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of medium accuracy class III and ordinary accuracy class IIII. They can also be used as control weights and are usually accompanied by a calibration certificate. MASSES FROM 100 kg to 2t E, F and M classes These masses are intended for use in the calibration of weights of a lower accuracy class and for use with weighing instruments of special accuracy class I, high accuracy class II and medium accuracy class III. They are usually accompanied by a calibration certificate. All these masses can be handled with slings to be fixed at the rings. M class weights with feet have been conceived to be stackable and can be handled with a forklift truck or pallet lift.
