Description
Knob weight M2 is an individual test weight for balance verification and routine metrological checks in laboratory settings. It belongs to the M2 accuracy class covering single weights from 1 g to 10 kg and is made from fine-turned brass. Weights up to 20 g are supplied in a plastic box, while pieces from 50 g are delivered in a wooden case; this unit has a net weight of 0,050 kg and a gross weight of 0,100 kg, consistent with wooden-case packaging. The fine-turned brass body offers a well-defined mass form suitable for everyday calibration and intermediate checks. Available from manufacturer Sartorius, the weight is supplied as one non-sterile piece for quality-control, service, and laboratory weighing workflows. German origin and clear class designation make it straightforward to place within existing M2 weight inventories. Use it for balance testing, documented verification steps, and general laboratory mass comparison where an M2 knob weight is required.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 50 g, OIML M2
What is this article?
Knob Weight 50 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.
