WEIGHT SETS CLASS F 2 Ohaus (30390835)

WEIGHT SETS CLASS F 2 Ohaus (30390835)

The WEIGHT SETS CLASS F 2 Ohaus (30390835) is a traceable calibration weight set designed for comprehensive verification of analytical balances and precision scales across a wide mass range. This set conforms to OIML Class F2 and includes an ISO/IEC 17025 accredited calibration certificate, making it suitable for laboratories and quality systems that require accredited traceability for audits and documented QA/QC routines. Covering 10 kg down to 1 mg, it supports multi-point linearity checks, repeatability verification, and sensitivity testing from kilogram to milligram levels. For practical handling and durability, weights of 1 g and above use a two-piece design, while 500 mg and below use a one-piece design for smaller, delicate values. The set is supplied in a protective case to help maintain cleanliness, organization, and safe transport. Made in the USA.
