Description
Individual weight 5 kg, class F2 is a precision test weight designed for reliable checking and adjustment of laboratory and industrial balances. Manufactured from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, it offers a defined density of 8,0 g/cm³ for stable metrological performance. This single weight belongs to the F2 individual-weight range covering 1 g to 50 kg and is supplied as one piece. For nominal values from 50 g upward the weight is presented in a wooden case that protects the finely finished surface during storage and transport; lighter pieces in the same series use a plastic box. The 5 kg unit (Sartorius) is suited to routine verification, intermediate checks and quality-control workflows where OIML class F2 accuracy is required. Its non-magnetic behaviour minimises interference in sensitive weighing environments, while the corrosion-resistant steel supports long service life under typical laboratory conditions. Net weight is 5,000 kg. Ideal for calibration laboratories, production QA and service technicians who need a durable, clearly specified reference mass.

Questions about Knob Weight 5 kg, OIML F2, DAkkS
What is this article?
Knob Weight 5 kg, OIML F2, DAkkS 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.
