Description
Knob weight E2 is a single calibration weight for precise checking of laboratory and industrial balances. This 100 g unit is manufactured from polished special steel that is non-magnetisable, offering reliable performance in everyday metrology. It belongs to the E2 individual-weight series spanning 1 g to 10 kg and is supplied in a plastic box. The classic knob geometry permits secure grip and stable seating on the weighing pan during verification procedures. Delivered as one piece with a net mass of 0,100 kg (gross mass 0,110 kg), the weight is ready for immediate use in quality-control, service and production environments where E2 tolerances are required. The polished special-steel surface supports clean handling and long service life under normal laboratory conditions. Produced by Sartorius, this reference mass complements existing calibration sets and supports consistent balance performance checks without the need for higher E1-class standards. It is intended for non-sterile ambient use and integrates smoothly into routine weighing-system maintenance workflows.

Questions about Knob Weight 100 g, OIML E2
What is this article?
Knob Weight 100 g, OIML E2 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Poids d'étalonnage & de contrôle, inside Balances et bascules, in Instruments de laboratoire.
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.
