Description
Knob weight E1 is a high-accuracy individual calibration weight for demanding laboratory and metrology applications. Covering the E1 single-weight range from 1 g to 50 kg, it is manufactured from special steel that is high-gloss polished, non-magnetizable, and highly corrosion-resistant, with a density of 8,0 g/cm³. Smaller pieces up to 20 g are packed in a plastic box; from 50 g the weight is supplied in a wooden case. This unit has a net weight of 0,100 kg and a gross weight of 0,260 kg. The polished special-steel construction supports stable, repeatable mass values for precision balance calibration and reference checks. Offered by manufacturer Sartorius as one non-sterile piece, the weight suits accredited laboratories, quality systems, and service environments that specify E1-class knob weights. German manufacture and clearly defined physical properties help integrate the piece into existing high-accuracy weight sets and documented calibration procedures.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 100 g, OIML E1
What is this article?
Knob Weight 100 g, OIML E1 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?
