Description
Knob weight class E1 is a high-accuracy single test weight for demanding calibration of precision balances and reference weighing systems. It covers the E1 individual-weight range from 1 g to 50 kg and is manufactured from special steel that is high-gloss polished, non-magnetizable, and highly corrosion-resistant, with a density of 8,0 g/cm³. Packaging follows size: pieces up to 20 g are supplied in a plastic box, while weights from 50 g are housed in a wooden case. The unit is offered as one piece with a net weight of 0,500 kg and a gross weight of 0,950 kg. This knob weight from manufacturer Sartorius is intended for metrology laboratories and controlled environments where E1-class reference masses are specified. Non-magnetizable, corrosion-resistant special steel with a polished finish supports stable long-term use in high-precision verification, adjustment, and quality-control workflows that depend on tightly controlled reference standards.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 500 g, OIML E1
What is this article?
Knob Weight 500 g, OIML E1 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.
