Description
F2 knob weight is an individual test weight intended for calibration and functional checks of balances in the F2 accuracy class. It is produced from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³ to ensure consistent mass behaviour. The F2 single-weight series spans 1 g to 50 kg; this knob-style piece has a net weight of 0,050 kg and is offered as one unit. Protective packaging follows the established scheme: plastic boxes for weights up to 20 g and wooden cases from 50 g upward, safeguarding the polished surface in laboratory and service use. The knob form facilitates secure handling during placement on balance pans and during intermediate verification routines. Typical applications include routine balance checks, quality assurance in production weighing and maintenance of weighing systems where F2 tolerance is specified. Supplied as a durable special-steel knob weight from manufacturer Sartorius, it supports reliable, low-interference calibration work in everyday laboratory practice.

Questions about Knob Weight 50 g, OIML F2
What is this article?
Knob Weight 50 g, OIML F2 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?
