Weights and Weight Sets

Scale Weights, Test Weights, and Calibration Weight Sets

Liberty Scales carries a complete selection of calibration weights, test weights, and scale weight sets for laboratory verification, legal-for-trade compliance, and industrial scale calibration. These are the reference masses used to verify that a weighing instrument is reading accurately before it goes into service or before a critical measurement run.

Our weight inventory spans Class 1 through Class 7 tolerances, with options in stainless steel, cast iron, and chrome-plated steel across a wide gram and kilogram range. We stock NVLAP-certified weight sets from recognized manufacturers for applications where documentation and traceability are required, including pharmaceutical, food processing, and legal-for-trade environments.

Test weights are available individually and in complete calibration weight sets with fitted carrying cases. Most orders ship same day. If you need to match a specific OIML or ASTM class to your scale's capacity and readability, contact our technical team at (661) 888-1919 or info@libertyscales.com and we will confirm the right class for your application.
