NSTAR Corp offers calibration weights from 1 mg to 500 kg. Available as assorted weights and weight sets in OIML E1-E2-F1-F2 and M1 accuracy classes. Calibration weights are available with ISO/IEC 17025 Accredited (NABL) calibration certificate.

NSTAR calibration weights are designed, so the specifications on surface finish, markings, construction, material density, and magnetic properties become more restrictive as the weight tolerances decrease in order to enable the weight to maintain its tolerance over time. These weights are manufactured for your most demanding and accurate weighing applications. Choose your OIML standard test weights for performance checks of your weighing balances daily.
