WEIGHT SETS CLASS F 2 Ohaus (30390848)

WEIGHT SETS CLASS F 2 Ohaus (30390848)

The WEIGHT SETS CLASS F 2 Ohaus (30390848) is a traceable calibration weight set for accurate verification of analytical balances and microbalances. Conforming to OIML Class F2 and supplied with an ISO/IEC 17025 accredited calibration certificate, this set supports documented calibration workflows in regulated and quality-driven laboratories. With a range from 100 g down to 1 mg, it enables multi-point linearity checks, sensitivity testing, and repeatability verification across gram-to-milligram measurements. For practical handling and stability, weights of 1 g and above use a two-piece design, while 500 mg and below use a one-piece design. A protective case is included to keep weights clean, organized, and protected during storage and transport. Made in the USA.
