Description
E2 knob weight is a precision single weight shaped for convenient handling during balance calibration and verification in the laboratory. It is manufactured from polished special steel that is non-magnetizable, supporting stable readings and reduced magnetic interference on sensitive weighing instruments. This individual weight forms part of the E2 single-weight series spanning 1 g to 10 kg and is delivered in a plastic box that protects the polished surface in storage and transit. Supplied as one piece with a net weight of 0,002 kg and a gross weight of 0,030 kg, it is suited to routine metrology tasks, quality-assurance checks and intermediate balance tests. The knob form allows secure placement and removal without excessive contact with the working surface of the mass. Available from manufacturer Sartorius, the weight fits laboratories that maintain E2-class reference sets for analytical and precision balances. Polished special-steel construction combines corrosion-conscious durability with clean handling characteristics under normal room-temperature laboratory conditions, making the knob weight a practical reference element for everyday calibration workflows.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 2 g, OIML E2
What is this article?
Knob Weight 2 g, OIML E2 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.
