Description
Knob weight is an E2 individual test weight for precise verification and calibration tasks in laboratory and industrial metrology. It is produced from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³ to support stable, repeatable mass values. This single piece belongs to the E2 individual-weight range from 1 g to 50 kg offered by manufacturer Sartorius. Units up to 20 g are supplied in a plastic box, while pieces from 50 g are delivered in a wooden case, protecting the polished surface during storage and transport. The net weight is 0,002 kg and the gross weight is 0,130 kg, giving a compact format suited to routine balance checks where E2-class performance is required. Non-magnetizable special steel helps limit magnetic interference in sensitive weighing environments, and the high corrosion resistance supports dependable long-term use under normal laboratory conditions. Originating from Germany (Baden-Württemberg), the weight is intended for professional test-weight applications in quality control, service and calibration workflows.

Questions about Knob Weight 2 g, OIML E2
What is this article?
Knob Weight 2 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.
