Description
F1 knob weight is an individual precision test weight for calibration and verification of laboratory balances. It belongs to the F1 single-weight range from 1 g to 10 kg and is manufactured from polished special steel that is non-magnetizable, helping to limit magnetic influence during sensitive mass determinations. The knob form supports secure, controlled handling with forceps or gloved hands, while the polished surface simplifies visual inspection and routine cleaning of the working faces. Each piece is supplied in a protective plastic box that shields the mass standard between uses and keeps it organised on the bench or in storage. Quality-control, analytical and industrial metrology laboratories can apply this class F1 reference within internal balance-check programmes and weighing assurance workflows. Offered as one piece with a net weight of 1,000 kg, the weight comes from manufacturer Sartorius and reflects a special-steel build chosen for dimensional stability and practical corrosion resistance in controlled laboratory environments where dependable F1 test masses are required day to day.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 1 kg, OIML F1
What is this article?
Knob Weight 1 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?
