Description
E1 knob weight is a high-accuracy individual test weight with a nominal mass of 30 g for demanding laboratory and metrology applications. It belongs to the E1 single-weight series spanning 1 g to 50 kg and is manufactured from special steel that is high-gloss polished, non-magnetisable and highly corrosion-resistant, with a stated density of 8,0 g/cm³. The knob geometry enables secure, controlled placement on precision balances during verification and calibration routines. Packaging follows the series rule: up to 20 g in a plastic box and from 50 g in a wooden case; at 30 g this unit is supplied in line with that E1 programme. Net weight is 0,030 kg and gross weight is 0,300 kg. Offered as 1 pc, the weight serves quality-control, accredited laboratory and research environments that require E1 class individual masses. Produced by Sartorius, it is intended for professional test-weight use where non-magnetisable, corrosion-resistant special steel and high-gloss finish are specified. Origin data point to Germany (Baden-Württemberg). Deploy it for fine balance checks, reference comparisons and metrological workflows that call for a clearly defined E1 knob weight in the multi-gram range.

Questions about Knob Weight 2 g, OIML E1, DAkkS
What is this article?
Knob Weight 2 g, OIML E1, DAkkS 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.
