The 1 kg Range Calibration Weight Set, OIML Class M1 is designed for dependable performance in routine calibration and verification environments. This set is ideal for laboratories and industrial facilities that require reliable working standards for daily weighing tasks rather than ultra-high precision reference weights.
Manufactured in accordance with OIML R111 international standards, the set includes individual M1 class calibration weights housed in a protective case for secure handling and long-term storage. Each weight is permanently marked with its nominal value for easy identification and traceability. With a material density of approximately 7.95 g/cm3, the set delivers stable and repeatable mass performance for quality control and verification processes.
For applications requiring enhanced identification or asset tracking, optional serial numbers may be stamped on weights 100 g and larger, available at an additional charge.
