Description
Knob weight E1 is a single high-accuracy test weight from the E1 series covering nominal values from 1 g to 50 kg. It is manufactured from special steel that is high-gloss polished, non-magnetisable and highly corrosion-resistant, with a density of 8,0 g/cm³ suited to precision mass metrology. E1 knob weights of this construction are intended for demanding calibration and verification of analytical and precision balances where the highest OIML accuracy class is required. Compact pieces up to 20 g are typically supplied in a plastic box, while values from 50 g upward are housed in a wooden case for protected storage and transport. This single-piece unit from manufacturer Sartorius has a net weight of 55 kg and a gross weight of 60 kg, reflecting the robust build of the larger E1 format. German origin and room-temperature storage complete a specification aimed at accredited laboratories, calibration services and quality systems that rely on stable, corrosion-resistant reference masses.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 50 kg, OIML E1, DAkkS
What is this article?
Knob Weight 50 kg, 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.
Which category should I open next?
