Description
E2 knob weight is an individual reference mass for calibration and verification of laboratory and industrial balances. It belongs to the E2 single-weight series covering nominal values from 1 g to 50 kg and is produced from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³. These material properties support stable mass behaviour and low magnetic susceptibility during precision weighing. Units up to 20 g are supplied in a plastic box, while weights from 50 g are housed in a wooden case for protected handling and storage. Offered as a single piece with a net weight of 0,500 kg, this knob-style weight from manufacturer Sartorius is intended for routine quality control, balance adjustment and metrological checks where a durable, corrosion-resistant E2 standard is required. The polished special-steel construction facilitates cleaning and long-term use in controlled laboratory environments without introducing unnecessary magnetic interference into the measurement process.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 500 g, OIML E2
What is this article?
Knob Weight 500 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.
Which category should I open next?
