Calibration Weight - 20g OIML F1

Stainless steel OIML calibration weights (masses), for the external calibration of electronic balances. These weights meet the requirements for testing to OIML standards (Organisation Internationale de Métrologie Légale / The International Organization of Legal Metrology). F1 weights provide a high level of accuracy and are ideal for calibrating analytical and precision balances with a readability of 0.001g and 0.01g. M1 weights provide a slightly lower level of accuracy, but are more economically priced, and are suitable for calibrating compact portable balances with a readability of 0.1g or less.
Even more precise E2 calibration weights, and complete M1 and F1 weight sets, can also be supplied on request.
