This Rice Lake 1 kg ASTM Class 3 Calibration Weight Set is engineered to serve as a dependable mass standard for a variety of precision applications. Its construction from polished stainless steel ensures long-term stability and resistance to environmental factors that could compromise accuracy, making it suitable for use in quality control labs, educational institutions, and production facilities.
The set is an essential tool for the calibration of Class I and II analytical and precision balances, as well as for the verification of ASTM Class 4, 5, and 6 weights. It is perfectly suited for routine verification checks, tolerance testing procedures, and rough weighing operations. In academic settings, it provides students with a hands-on understanding of mass standards and calibration principles. Each weight is clearly marked with its nominal value, and the set is accompanied by a serialized case for proper documentation and traceability within a quality system.
For specific requirements beyond this standard configuration, custom calibration weight sets are available as build-to-order items. Please note that ASTM weight sets with a largest weight exceeding 500 g include a protective hardwood case with velvet-lined pockets, while sets with a 500 g largest weight are housed in a precision-machined, polyvinyl crush-resistant case.
