Description
Knob weight M2 is a single calibration weight for routine verification of balances and scales in laboratory and industrial settings. This 50 g piece is produced from finely turned brass and belongs to the M2 individual-weight series spanning 1 g to 10 kg. The knob form factor allows secure handling and stable placement on the weighing pan during checks. Supplied as one piece with a net mass of 0,050 kg (gross mass 0,100 kg), the weight is delivered in a wooden case, consistent with the packaging scheme used for pieces from 50 g upward; smaller members of the same line up to 20 g are packed in plastic boxes. The brass construction offers a durable, traditional reference mass suited to quality-control, service and educational environments where OIML M2 tolerances are specified. Manufactured by Sartorius, the weight supports everyday metrology tasks without requiring higher-class stainless-steel standards. It is intended for non-sterile use at ambient conditions and integrates readily into existing calibration workflows for balances and scales.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 50 g, OIML M2, DAkkS
What is this article?
Knob Weight 50 g, OIML M2, DAkkS 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.
