Product Description
Choose the exact OIML class, mass value and certificate level your quality system calls for, without paying for weights you will never use. These individual weights cover milligram through 50 kg values across Classes E1, E2, F1 and F2, from reference-level mass standards to working weights for routine balance verification. They suit metrology labs, QC departments and service technicians who maintain their own weight inventories.
This listing is for OHAUS item number 30390869: OIML Class F2 Calibration Weight, 200 mg, One-Piece, No Certificate. Each gram and kilogram weight has a cylindrical profile with a tapered neck, a mirror-polished finish and a recessed base, and milligram weights are flat with a turned-up edge for tweezer handling. Gram and kilogram values use high-density Alloy 8 stainless steel or 316 stainless steel, and small milligram values use 304 stainless steel or aluminum to keep their size practical. Weights are listed as one-piece or two-piece, and come with an ISO/IEC 17025 accredited calibration certificate or no certificate as named. A fitted protective case is included with each weight. LIGHT LABS ships genuine OHAUS products and can help you match accessories and parts to your instrument.
