What Are E Class Calibration Weights?

E Class calibration weights refer to highly precise weights that conform to OIML R111 standards. These weights are commonly used to calibrate analytical balances and precision instruments, with E1 being the most accurate class.

• E1 Weights: Ideal for primary standards, offering the highest precision. Typically used in national metrology institutes.

• E2 Weights: Suitable for calibrating high-resolution analytical balances with a readability of 0.1 mg to 0.01 mg.

These weights are especially critical in industries like pharmaceuticals, biotech, chemical testing, and advanced material sciences.
