Description
E1 knob weight is a high-accuracy individual test weight intended for demanding calibration and verification of precision balances. It is produced from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³. The E1 single-weight series spans nominal values from 1 g to 50 kg and is aimed at metrology rooms, accredited laboratories and applications that specify the tightest OIML E1 tolerances. Product data list a net weight of 1,400 kg and a gross weight of 1,500 kg. In this range, units up to 20 g are delivered in a plastic box, while pieces from 50 g are housed in a wooden case for secure storage and transport. The polished, non-magnetic special-steel construction limits magnetic influence on sensitive weighing cells and supports long-term stability under repeated use. Available from manufacturer Sartorius, this knob-style mass standard fits internal quality systems and calibration routines that rely on E1 class reference weights for analytical and precision weighing instruments.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 1 kg, OIML E1, DAkkS
What is this article?
Knob Weight 1 kg, OIML E1, 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.
