Description
Knob weight E1 is a high-accuracy single test weight for demanding calibration and verification of precision balances in the E1 accuracy class. This unit has a nominal mass of 6 kg and is manufactured from special steel that is high-gloss polished, non-magnetisable and highly corrosion-resistant, with a density of 8,0 g/cm³. It belongs to the E1 single-weight range from 1 g to 50 kg. In this series, weights up to 20 g are supplied in a plastic box, while pieces from 50 g—including this 6 kg weight—are delivered in a wooden case. The polished special-steel construction supports stable reference use in controlled metrology environments where E1 performance is required. Available as an individual weight from manufacturer Sartorius, it suits accredited laboratories, calibration benches and high-end quality-control workflows. Net weight is 6,000 kg; gross weight including packaging is 6,800 kg. The wooden case protects the high-gloss surface during storage and transfer between weighing stations, helping preserve the integrity of the 6 kg E1 reference mass in daily laboratory practice.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 5 kg, OIML E1, DAkkS
What is this article?
Knob Weight 5 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.
