Description
Knob weight F2 is an individual precision test weight for calibration and checking of laboratory and industrial balances. Covering the F2 single-weight series from 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 design supports secure handling during placement on the weighing pan, while the polished, non-magnetic surface helps reduce unwanted influences on the measurement. Packaging follows the series convention: plastic box up to 20 g and wooden case from 50 g upward, protecting the working surfaces between uses. Supplied as one piece with a net weight of 2,500 kg, this knob weight from manufacturer Sartorius is suited to quality-control laboratories, analytical workflows and production metrology where F2-class individual masses are required. Durable special-steel construction and high corrosion resistance support repeated handling in controlled environments. The defined density and high-gloss finish contribute to consistent mass-standard performance for routine verification tasks on the bench or in the calibration room.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 2 kg, OIML F2
What is this article?
Knob Weight 2 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.
