Description
Knob weight E2 is a precision individual test weight for calibration and routine verification of laboratory balances and weighing instruments. It belongs to the E2 single-weight range covering 1 g to 10 kg and is produced from polished special steel that is non-magnetizable. Each piece is supplied in a plastic box for convenient storage and protection during transport and daily handling. Available as a single unit from manufacturer Sartorius, this knob weight supports checking of analytical balances, precision scales and related equipment in research, quality-control and industrial laboratories. The polished special-steel surface facilitates clean handling, while the non-magnetizable material helps maintain reliable weighing results under normal laboratory conditions. Use it for performance testing, adjustment verification and comparative mass measurements wherever E2-class individual reference weights are required. Compact packaging and robust construction make the weight practical for both benchtop metrology work and organised weight sets within documented laboratory quality programmes.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 1 g, OIML E2
What is this article?
Knob Weight 1 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.
