Description
Knob weight E1 is a high-accuracy single test weight for demanding calibration and verification of precision balances. It belongs to the E1 individual-weight range from 1 g to 50 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. Series packaging places pieces up to 20 g in a plastic box and pieces from 50 g in a wooden case. This unit has a net weight of 0,450 kg and a gross weight of 0,600 kg including packaging, supporting stable handling on the balance pan. E1 knob weights are chosen in metrology laboratories, accredited calibration facilities and quality-critical production settings where the highest conventional accuracy class is required. The polished special-steel construction maintains surface integrity and magnetic neutrality for sensitive weighing systems. This single weight from manufacturer Sartorius originates from Germany and suits professional mass-standard workflows. One piece is supplied per pack for use as a primary working reference or within comprehensive E1 test-weight sets.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 200 g, OIML E1, DAkkS
What is this article?
Knob Weight 200 g, 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.
