Description
Knob weight in accuracy class E2 provides an individual precision mass piece for verification and calibration of laboratory and industrial balances. Made from polished special steel that is non-magnetizable, it forms part of the E2 single-weight range from 1 g to 10 kg. Each unit is supplied as one piece in a protective plastic box that shields the polished surfaces in storage and transit. Product data list a net weight of 0,005 kg and a gross weight of 0,020 kg. The special-steel body from manufacturer Sartorius offers a smooth polished finish together with non-magnetizable behaviour, which supports reliable mass comparison on analytical and precision scales. E2 knob weights are widely used in quality-control labs, metrology rooms and service workshops that depend on defined tolerance classes. Non-magnetizable construction helps limit magnetic influence on the weighing result, and the polished exterior simplifies cleaning and visual checks for wear. This reference weight slots easily into existing test sets and everyday balance performance checks.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 5 g, OIML E2, DAkkS
What is this article?
Knob Weight 5 g, OIML E2, 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.
Which category should I open next?
