M1 Class Test Weights: The most widely used test weight available, mainly used for calibration where exact precision is not needed. All class III scales will use these.
F1 Class Test Weights: Used for standard precision balances & scales, these weights are highly accurate but more cost effective than E1 & E2 classes.
E2 Class Test Weights: The most precise test weights available to be used on balances and scales with very fine resolutions, such as micro and analytical balances.
