Description
M2 knob weight is a single test weight for calibration and verification of balances and scales in laboratory and industrial metrology. This 2 kg unit is made from finely turned brass and belongs to the M2 accuracy class in the single-weight range from 1 g to 10 kg. The knob form supports secure handling when the mass is placed on or lifted from a weighing pan during routine checks. Within this series, pieces up to 20 g are supplied in a plastic box and weights from 50 g upward are housed in a wooden case, so this brass weight is presented in a wooden case. Manufacturer Sartorius offers these M2 individual weights for everyday reference-mass tasks where a durable brass construction is specified. Finely turned brass provides a stable, traditional body suited to quality-control workflows, service laboratories and production areas that maintain weighing equipment to M2 tolerances. The article is supplied as one piece, with a net weight of 2,000 kg and a gross weight of 2,090 kg including packaging, and is intended for periodic balance verification without further accessories beyond standard knob-weight handling practice.
This article is part of Calibration & test weights, in Balances & scales.

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