Description
Knob weight M2, 50 g is a single test weight intended for checking and adjusting laboratory and industrial balances within the M2 accuracy class. With a net mass of 0,050 kg, this finely turned brass knob weight belongs to the M2 single-weight range covering 1 g to 10 kg. From 50 g upward the piece is supplied in a wooden case, protecting the polished working surfaces during storage and transport; smaller pieces in the same series use a plastic box. The compact knob form allows secure handling with forceps or gloved fingers and stable seating on the weighing pan. Manufactured by Sartorius, the weight supports routine verification work, intermediate checks and quality-control procedures where M2 tolerance is specified. Gross weight of the packaged unit is 0,400 kg. Originating from Germany (Baden-Württemberg), the product is non-sterile and suited to standard laboratory environments. Use it as a durable reference mass for balance performance monitoring, service intervals and documented weighing processes that require a clearly identified M2 brass knob weight of 50 g.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 20 g, OIML M2
What is this article?
Knob Weight 20 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.
