Description
Weight set, 500 mg–1 mg, OIML M1 is an OIML scale calibration weight set covering the milligram range from 1 mg to 500 mg for fine balance verification in laboratory and industrial settings. Built to OIML accuracy class M1, the set provides the discrete reference masses needed for multi-point checks on analytical and precision balances where M1 tolerance is specified. Piece composition includes 1 × 1 mg, 2 × 2 mg, 1 × 5 mg, 1 × 10 mg, 2 × 20 mg, 1 × 50 mg, 1 × 100 mg, 2 × 200 mg and 1 × 500 mg, corresponding to a combined net weight of 0,00111 kg. Gross weight of the packaged set is 0,41111 kg. Outer packaging measures 0,235 m in depth, 0,185 m in width and 0,048 m in height, with a packaging volume of 0,002 m³. The product originates from France. Offered from manufacturer Ohaus within the OIML scale calibration weight sets range and supplied as one complete set, this M1 milligram kit supports metrology workflows that depend on compact, class-compliant test weights for routine scale calibration and quality assurance.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight Set, 500mg-1mg, OIML M1
What is this article?
Weight Set, 500mg-1mg, OIML M1 is the article on this page. Luminix Health distributes Ohaus for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Instruments de laboratoire.
A test weight is a mass of a stated class, used to check a balance. The class sets the tolerance. A weight that is dirty, or that has been handled with bare fingers, is no longer that class. The certificate ties the weight to a standard.
A balance compares a mass with a standard. An analytical balance reads to 0.1 mg or finer and needs a draft shield and a stable bench. A precision balance is coarser and faster. A platform scale takes a heavier load. The reading is only as good as the calibration chain back to the kilogram, which is why test weights and a certificate exist. A moisture analyser is a balance with a heater: it records the loss of mass as water leaves. The unit of mass is kept by the BIPM, compared across Europe by EURAMET, and accredited by BELAC. NIST publishes the same measurement foundations.
