Description
F1 knob weight is a precision single weight configured for reliable balance calibration and verification tasks in the laboratory. Fabricated from polished special steel and specified as non-magnetizable, it forms part of an F1 single-weight series spanning nominal values from 1 g to 10 kg. The knob design facilitates secure handling with tweezers or weight forks while protecting working surfaces during placement on the balance pan. Each weight is delivered in a plastic box that shields the polished finish from dust and mechanical damage between uses. Offered as 1 pc with a net weight of 0,030 kg, the piece supports routine quality assurance, instrument checks and metrological control of precision and analytical balances. Material selection and surface polish from manufacturer Sartorius contribute to durable performance and long-term mass stability under standard laboratory conditions. The non-magnetizable special steel helps minimise magnetic interactions that could otherwise influence weighing results. This knob weight is intended for controlled environments where repeatable calibration and careful handling of reference masses are essential to measurement quality.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 2 g, OIML F1
What is this article?
Knob Weight 2 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?
