Description
Knob weight M2 is a single test weight for calibration and verification of balances in laboratory and industrial environments. It belongs to the M2 individual-weight series covering nominal values from 1 g to 10 kg and is produced from finely turned brass. Protective packaging follows the series standard: pieces up to 20 g are supplied in a plastic box, while weights from 50 g are housed in a wooden case to support safe handling and storage. This unit is offered as 1 piece, with a net weight of 0,200 kg and a gross weight of 0,500 kg. The design suits routine mass checks, quality-control workflows and comparative weighing where M2 tolerance is specified. Manufactured by Sartorius in Germany (Baden-Württemberg), the weight provides a durable brass body suited to everyday metrology tasks. Room-temperature storage is appropriate for normal laboratory conditions. Use it as a dedicated reference piece within established calibration procedures for balances and scales that require M2-class knob weights.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 100 g, OIML M2
What is this article?
Knob Weight 100 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.
