Description
M2 knob weight is an individual test weight for balance verification and general laboratory or workshop weighing control. Available as single pieces in the nominal range from 1 g to 10 kg, it is produced from finely turned brass in a classic knob form that is easy to handle during calibration routines. Packaging is matched to mass: units up to 20 g come in a plastic box, while pieces from 50 g are housed in a wooden case for secure keeping and transport. The M2 accuracy class addresses applications that require a defined, economical reference mass for routine checks, service work and quality monitoring. Finely turned brass gives a stable, serviceable construction suited to everyday metrology use. This individual weight from manufacturer Sartorius supports flexible build-up or replacement of M2 inventories without purchasing complete sets. Supplied as 1 pc, it fits calibration kits, teaching labs and industrial stations where single knob weights of class M2 are specified for intermediate checks and documented weighing control.
This article is part of Calibration & test weights, in Balances & scales.

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