Description
F2 knob weight is a precision single weight designed for checking and adjusting laboratory balances and related weighing systems. It forms part of the F2 individual-weight series spanning nominal values from 1 g to 10 kg and is delivered as one piece in a plastic box. The weight is manufactured from special steel that is finely ground and non-magnetisable, giving a stable, low-magnetic reference mass suitable for routine verification work. The fine surface finish supports clean handling and helps preserve metrological performance between calibrations. This knob-style design from manufacturer Sartorius is intended for quality-control, analytical and production laboratories that require class F2 accuracy in compact single-weight form. Non-magnetisable special steel reduces magnetic interference during sensitive comparisons, while the protective plastic box aids orderly storage and transport. Net weight for this unit is 0,100 kg. The combination of F2 tolerance class, finely ground special steel and practical packaging makes the weight a reliable choice for everyday balance checks and mass-standard workflows.

Questions about Knob Weight 100 g, OIML F2
What is this article?
Knob Weight 100 g, OIML F2 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?
