Description
F2 knob weight is a precision test weight designed for calibration and verification of balances and scales in laboratory and industrial settings. Belonging to the F2 single-weight series spanning 1 g to 50 kg, it is manufactured 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 factor supports secure grip and controlled placement on weighing pans during everyday metrology tasks. Units up to 20 g are delivered in a plastic box; from 50 g upward they are supplied in a wooden case that shields the polished surface. Available from manufacturer Sartorius, this knob weight is suited to quality control, service laboratories and production lines that require OIML F2 class reference masses. Offered as a single piece, it enables targeted replacement of individual denominations or flexible build-up of custom weight sets. Robust special-steel construction and non-magnetic behaviour support reliable use with precision and industrial balances under typical room-temperature laboratory conditions.
This article is part of Calibration & test weights, in Balances & scales.

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