Product Description
For labs that test balances right down to the milligram range, these OHAUS OIML sets combine kilogram, gram and milligram weights in one case, so the full calibration sequence can be run without mixing sources. Every set ends at 1 mg, tops out anywhere from 200 g to 50 kg, and comes in OIML classes E1, E2, F1 or F2.
This listing is for OHAUS item number 80780451: OIML Class F1 Calibration Weight Set, 2 kg to 1 mg, with Accredited Calibration Certificate. All sets ship with an ISO/IEC 17025 accredited calibration certificate and a protective case. Weights of 1 g and above are two-piece with a tapered neck, polished mirror-like finish and recessed base, while weights of 500 mg and below are one-piece and flat with one upturned end for tweezer handling. Materials include Alloy 8 stainless steel for gram weights, stainless steel for milligram weights from 500 mg to 5 mg, aluminum below 5 mg and 316 stainless steel for larger kilogram masses, and every set is made in the USA.
