Product Description
Calibrating a balance across its whole range is far quicker when every test value you need sits in one fitted case. These OHAUS OIML weight sets span compact 500 mg to 1 mg milligram kits up to 20 kg to 1 g sets, in accuracy classes E1, E2, F1 and F2, so a single purchase can cover a microbalance, an analytical balance or a high-capacity precision balance.
This listing is for OHAUS item number 80780454: OIML Class F1 Calibration Weight Set, 5 kg to 1 g, with Accredited Calibration Certificate. Gram weights feature a tapered neck for secure handling, a polished mirror-like finish that makes scratches or contamination easy to spot, and a recessed base that reduces wear; milligram weights are flat with one end turned up for pick-up with tweezers. Weights of 1 g and above are two-piece and those of 500 mg and below are one-piece, with materials that include Alloy 8 stainless steel, 316 stainless steel and aluminum depending on size. Every set comes in a protective case and is made in the USA, with E-class sets supplied with ISO/IEC 17025 accredited certificates and F-class sets available with or without accredited certification.
