Description
M2 knob weight is a single calibration weight intended for routine checking and adjustment of balances in laboratory and industrial weighing applications. Belonging to the M2 single-weight series covering nominal values from 1 g to 10 kg, it is manufactured from finely turned brass for stable mass and reliable everyday performance. Up to 20 g the weights are supplied in a plastic box; from 50 g they are housed in a wooden case for secure storage and transport. This unit is offered as a single piece with a net weight of 6,800 kg and a gross weight of 7,700 kg, making it suitable for heavier reference work within the stated range. Produced by manufacturer Sartorius, the weight supports quality-control and verification tasks where M2-class accuracy is specified. Its robust brass construction and protective packaging help maintain integrity during repeated handling in calibration laboratories, production environments and metrology workshops. The product is non-sterile and originates from Germany, providing a practical reference standard for balance testing without additional performance claims beyond the stated M2 class and material specification.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 5 kg, OIML M2, DAkkS
What is this article?
Knob Weight 5 kg, 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.
