Description
E2 knob weight is a precision single weight designed for the calibration and checking of balances and scales in laboratory and industrial metrology. It belongs to the E2 class of individual weights covering 1 g to 10 kg and is made from special steel that is polished and non-magnetizable, helping to maintain mass stability and low magnetic susceptibility in use. The knob form factor supports secure grip and controlled placement on weighing pans. Each weight is delivered in a plastic box that shields the polished finish during storage and transport. Offered as a single 0,020 kg piece, the unit is appropriate for routine calibration sequences, quality-assurance measurements and ongoing instrument verification. Special-steel construction from manufacturer Sartorius combines a polished surface with non-magnetizable behaviour for dependable day-to-day reference work. Sites that operate calibrated weighing equipment can add the knob weight to their test-weight sets to support consistent performance checks across laboratory and production workflows.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 20 g, OIML E2, DAkkS
What is this article?
Knob Weight 20 g, OIML E2, DAkkS 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?
