Description
Knob weight E2 is a precision single test weight for calibration and verification tasks on laboratory and industrial weighing instruments. It belongs to the E2 individual-weight series covering nominal values from 1 g to 50 kg and is manufactured from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³. As with the series standard, weights up to 20 g are delivered in a plastic box, while pieces from 50 g are packed in a wooden case for protection during storage and transport. Supplied as 1 piece, this unit has a net weight of 0,200 kg and a gross weight of 0,310 kg. The combination of E2 accuracy class, stable density and corrosion-resistant finish supports reliable mass comparison and balance checks. Produced by Sartorius in Germany (Baden-Württemberg), the weight is suitable for routine metrology and quality-control applications. Room-temperature storage is appropriate. Use it wherever E2-class knob weights are specified for instrument verification and reference weighing.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 200 g, OIML E2
What is this article?
Knob Weight 200 g, 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.
