Description
E2 knob weight is a precision individual test weight for calibration and verification of balances and mass comparators in laboratory and industrial metrology. This single piece has a nominal mass of 10 kg and belongs to accuracy class E2. It is made from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³. These material properties support stable handling while limiting magnetic influence on sensitive weighing instruments. Supplied as 1 piece, the weight is delivered in a wooden case, in line with the packaging used for individual pieces from 50 g upward within this family covering 1 g to 50 kg. The knob geometry allows secure placement and removal during routine checks. This individual weight from manufacturer Sartorius suits quality-control laboratories, calibration workshops and production environments that maintain E2-class reference standards. High surface finish and corrosion resistance help preserve the mass piece between uses when handled under good laboratory practice. The net mass of 10 kg matches the stated value for this catalogue variant and supports coherent reference sets alongside other E2 individual weights.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 10 kg, OIML E2
What is this article?
Knob Weight 10 kg, 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.
Which category should I open next?
