Description
M2 knob weight is an individual calibration weight for checking balances and scales in laboratory and industrial metrology. It belongs to the M2 single-weight series spanning 1 g to 10 kg and is produced from finely turned brass, giving a durable, easy-to-handle reference mass in classic knob form. This unit has a net weight of 0,020 kg and is supplied as one piece; weights up to 20 g are delivered in a plastic box, while pieces from 50 g upward are housed in a wooden case, matching the packaging scheme of the range. The brass construction is suited to routine verification work where M2-class tolerances are specified. Gross weight of the packaged item is 0,300 kg. Offered by manufacturer Sartorius, the weight supports quality-control, service and production environments that rely on stable mass standards. Origin is Germany (Baden-Württemberg). Use it as a practical single reference mass whenever an M2 knob weight in this size class is required for balance checks and related metrological tasks.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 2 g, OIML M2
What is this article?
Knob Weight 2 g, OIML M2 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.
