About OIML E1 & E2 Test / Calibration Weights & Sets

OIML Class E1 calibration weights are commonly used for calibrating other weight references and are suitable for calibrating high-precision balances. They are constructed in the piece so there is no method of adjustment.

OIML Class E2 calibration weights can be used as a reference standard for calibrating other weights and calibrating high-precision analytical balances with a readability as low as 0.1 mg to 0.01 mg.
