WEIGHT SETS CLASS F 2 Ohaus (30390036)

WEIGHT SETS CLASS F 2 Ohaus (30390036)

The WEIGHT SETS CLASS F 2 Ohaus (30390036) is a precision calibration weight set designed for routine verification of analytical balances and microbalances. Conforming to OIML Class F2, this set spans from (2) 200 g down to 1 mg, making it suitable for multi-point linearity checks, sensitivity testing, and repeatability verification across gram-to-milligram ranges. The set uses a practical mixed construction: two-piece weights for 1 g and above, and one-piece weights for 500 mg and below, supporting stable handling while minimizing the risk of damage at smaller values. A protective case is included to keep all weights clean, organized, and protected during storage and transport. Made in the USA.
