Description
Knob weight M1 is a single test weight intended for verification and routine checking of laboratory and industrial balances in the M1 accuracy class. This piece has a nominal mass of 2 kg and is manufactured from galvanised brass, offering a durable working surface for everyday metrology use. It forms part of the M1 single-weight family covering 1 g to 10 kg and is supplied in a plastic box that shields the weight during storage and handling between workstations. Such knob weights support intermediate checks, performance verification and simple mass comparison where M1 tolerances are specified. The galvanised brass construction is suited to regular laboratory handling under normal ambient conditions. Offered as an individual unit from manufacturer Sartorius, the weight fits quality-control benches and service sets that need a stable 2 kg reference mass. Net weight is 2,000 kg; gross weight including packaging is 2,080 kg. The protective plastic box keeps the knob geometry and contact surfaces ready for repeated use without unnecessary exposure during transport within the laboratory.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 2 kg, OIML M1, DAkkS
What is this article?
Knob Weight 2 kg, OIML M1, 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.
