Product Description
Keep balance checks defensible during audits by verifying against an OIML weight in exactly the class and denomination your SOP specifies. E1 weights are suited to primary reference work and to calibrating balances readable to 0.1 mg, E2 weights support transfer to lower classes, and F1 and F2 weights cover everyday precision balance verification. Buying individual values lets you fill gaps in an existing set or dedicate one weight to a single instrument.
This listing is for OHAUS item number 30390861: OIML Class F2 Calibration Weight, 100 g, Two-Piece, No Certificate. Weights of 1 g and above have a cylindrical body with a tapered handling neck, a polished surface and a recessed bottom, while milligram weights are flat wire-style pieces with an upturned end. Construction is noted in each item name: one-piece designs have no adjusting cavity, and two-piece designs have a threaded knob over an adjustment cavity. Gram and kilogram values are made from Alloy 8 or 316 stainless steel, and milligram values from 304 stainless steel or aluminum. Certificate options are ISO/IEC 17025 accredited or none, depending on the item, and a protective case is included. Order it from LIGHT LABS alongside the rest of your OHAUS balances, weights and lab equipment.
