Its construction from high-quality, non-magnetic stainless steel ensures durability and resistance to corrosion, preserving its mass value over time. The weight features a sealing cavity, allowing for official adjustment by an accredited laboratory to maintain its precise nominal value.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eThe primary application for this weight is the calibration and routine verification of high-resolution Class I and Class II analytical and precision balances. By providing a known, traceable mass standard, technicians can confidently verify balance performance, perform tolerance checks, and ensure compliance with internal quality protocols and external regulatory requirements, such as those outlined in NIST Handbook 44.
