Description
F1 knob weight is a precision individual test mass intended for calibration and verification of balances in laboratory and industrial settings. It belongs to the F1 individual-weight series covering 1 g to 50 kg and is produced from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³. The knob form supports secure handling during placement and removal on the weighing pan, while the material specification helps maintain mass stability and minimise magnetic interference. Weights up to 20 g are delivered in a plastic box; from 50 g upward they are housed in a wooden case. Supplied as 1 pc with a net weight of 24,000 kg, this knob weight from manufacturer Sartorius is suited to routine adjustment, quality-assurance checks and reference work where F1-class accuracy is specified. High corrosion resistance and a polished finish facilitate cleaning and repeated use, supporting reliable metrology workflows that depend on durable special-steel test weights with clearly defined density and non-magnetizable behaviour.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 20 kg, OIML F1
What is this article?
Knob Weight 20 kg, OIML F1 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?
