Description
Wire weight E2 is a precision single weight for laboratory calibration and balance verification covering individual masses from 1 mg to 500 mg. It is produced from non-magnetisable special steel with a density of 8,0 g/cm³ and high corrosion resistance, giving a durable reference mass for everyday metrological use. The unit is supplied as one piece in a plastic box for protected storage and convenient handling at the weighing bench. Offered by manufacturer Sartorius, this E2-class wire weight supports quality systems that specify E2 individual weights for checking analytical and precision balances. Net weight is 0,030 kg. Non-magnetisable special steel and a corrosion-resistant surface help maintain consistent mass values during repeated use, while the plastic box reduces the risk of mechanical damage or contamination between calibration sessions in research, industrial and quality-control laboratories.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Wire Weight 500 mg, OIML E2
What is this article?
Wire Weight 500 mg, OIML E2 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Lab instruments.
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.
