Class M1, M2 & M3 Calibration Weights

Calibration weights are reference objects used for the calibration, verification and adjustment of weighing instruments such as laboratory, industrial or commercial balances. They are manufactured to strict precision standards and play an essential role in the metrological traceability of mass measurements.

They are made from stable, corrosion-resistant materials (stainless steel, brass, treated cast iron) and are often supplied with a calibration certificate issued by an accredited laboratory (COFRAC or equivalent), guaranteeing their accuracy and compliance.

Class M1, M2 & M3 calibration weights are used for the calibration of less sensitive industrial or commercial balances. They are available in the various accuracy classes defined by the OIML (International Organization of Legal Metrology) standards. Please contact us to discover all our models.
