Description
Knob weight F1 is a single test weight for calibration and verification tasks in laboratory and industrial weighing. It belongs to the F1 single-weight range from 1 g to 10 kg and is made from polished special steel that is non-magnetisable, supporting stable mass comparison with low magnetic influence. Supplied as one piece in a protective plastic box, the knob form allows secure handling during routine balance checks and quality-control work. The polished special-steel construction from manufacturer Sartorius suits metrology workflows where surface finish and clean handling matter. Net weight is 0,005 kg and gross weight 0,030 kg including packaging, so the unit remains compact for storage and transport. Typical applications include verification of analytical and precision balances, reference mass handling, and periodic performance checks in controlled laboratory environments. The non-magnetisable material helps limit magnetic interference during sensitive weighing, while the plastic box protects the weight between uses and keeps the set organised on the bench or in the calibration store.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 5 g, OIML F1
What is this article?
Knob Weight 5 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?
The category is Balances & scales. The sub-category is Calibration & test weights. The catalogue is Lab instruments.
