Description
Knob weight E2, 50 g is a single test weight designed for calibration, adjustment and routine verification of laboratory balances operating under E2 accuracy requirements. Net mass is 0,050 kg. The weight is produced from non-magnetisable special steel with a density of 8,0 g/cm³, finished to a high-gloss polish and offering high corrosion resistance for stable long-term use. Within the E2 single-weight series from 1 g to 50 kg, pieces from 50 g are supplied in a wooden case, while smaller denominations up to 20 g are packed in a plastic box. The knob shape provides secure grip and reproducible positioning on the balance pan during comparative weighing. This model from manufacturer Sartorius suits quality-control laboratories, service workshops and production environments that specify E2 reference weights. Gross weight of the packaged article is 0,200 kg. Origin is Germany (Baden-Württemberg); the product is non-sterile and intended for room-temperature storage. Deploy it for intermediate checks, balance performance monitoring and documented metrological control whenever an E2 special-steel knob weight of 50 g is needed.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 50 g, OIML E2
What is this article?
Knob Weight 50 g, OIML E2 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.
