WEIGHT SETS CLASS F 2 Ohaus (30390850)

The WEIGHT SETS CLASS F 2 Ohaus (30390850) is a precision calibration weight set designed for routine verification and performance checks of analytical balances and microbalances. Conforming to OIML Class F2, this set covers 50 g down to 1 mg, enabling multi-point linearity, sensitivity, and repeatability checks across gram-to-milligram weighing. The mixed construction supports practical handling: two-piece weights for 1 g and above, and one-piece weights for 500 mg and below. A protective case is included to keep the weights organized and protected from contamination during storage and transport. Made in the USA.
