INDIVIDUAL WEIGHT CLASS F 2 Ohaus (30390880)

INDIVIDUAL WEIGHT CLASS F 2 Ohaus (30390880)

The INDIVIDUAL WEIGHT CLASS F 2 Ohaus (30390880) is a precision 5 kg calibration weight designed for accurate verification and routine calibration of precision balances and laboratory/industrial scales. Conforming to OIML Class F2, this weight supports consistent weighing accuracy for calibration rooms, warehouses, production QC, and laboratory environments. It is suitable for documented calibration routines such as multi-point linearity checks and periodic performance validation at kilogram ranges. The cylindrical design provides stable placement and repeatable handling, while the two-piece construction improves durability and long-term stability. A protective case is included to help protect the weight from dust, contamination, and physical damage during storage and transport.
