Description
F1 knob weight is an individual test weight intended for laboratory balance checking and calibration workflows. It forms part of the F1 single-weight range covering nominal values from 1 g to 10 kg and is manufactured from polished special steel that is non-magnetizable. The polished finish supports clean handling during routine metrology use, while the non-magnetizable steel construction helps reduce magnetic interference in sensitive weighing operations. Each unit is supplied in a plastic box that protects the weight in storage and during transfer between laboratory stations. This configuration specifies a net weight of 0,001 kg and a gross weight of 0,020 kg and is offered as a single piece for dedicated test-weight inventories or individual replacement. Laboratories employ F1-class knob weights when verifying analytical and precision balances and when maintaining internal mass references under controlled conditions. This knob weight from manufacturer Sartorius is aimed at professional quality-assurance, research and industrial laboratory settings. Pack size is 1 pc, aligned with typical single-weight replenishment for F1 test-weight collections used in balance testing and intermediate checks.
This article is part of Calibration & test weights, in Balances & scales.

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