Product Description
A complete, matched set of OIML weights turns periodic balance testing into a fast, repeatable routine instead of a hunt for loose masses. This group of OHAUS sets runs from 50 g to 1 g bench kits through 50 kg to 1 mg master sets, plus a dedicated 5 kg to 1 kg set for large-capacity checks, in OIML classes E1, E2, F1 and F2.
This listing is for OHAUS item number 80780418: OIML Class F1 Calibration Weight Set, 500 g to 1 mg, No Certificate. Sets are organized in a fitted protective case, with each weight in its own pocket to prevent contact damage. Gram and kilogram weights have a tapered neck, a polished mirror-like finish and a recessed base, while milligram pieces are flat with an upturned edge for easy tweezer handling. Depending on the set, weights are made from Alloy 8 stainless steel, 316 stainless steel and aluminum for the smallest milligram values; sets marked no certificate ship uncertified, and accredited versions include an ISO/IEC 17025 calibration certificate. All are manufactured in the USA. LIGHT LABS supplies the OHAUS line with knowledgeable support from our Englewood, Colorado team.
