Description
F2 knob weight is a precision individual mass standard for calibration and verification of balances and scales in laboratory and industrial settings. It belongs to the F2 accuracy class and is offered as an individual knob weight covering nominal values from 1 g to 50 kg. The weight is manufactured from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³, supporting stable reference values and low magnetic susceptibility during weighing. Pieces up to 20 g are supplied in a plastic box, while weights from 50 g are presented in a wooden case to safeguard the polished surface in storage and transit. Supplied as a single-piece pack from manufacturer Sartorius, this knob weight is well suited to routine instrument checks, quality-assurance tasks and metrological confirmation work. The corrosion-resistant special-steel build, defined density and protective packaging provide a practical reference mass for laboratories and production areas that require durable F2-class individual weights for organised calibration and verification routines.

Questions about Knob Weight 10 kg, OIML F2
What is this article?
Knob Weight 10 kg, 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?
