Description
Knob weight E2 is a single calibration weight for accurate verification and adjustment of laboratory balances and precision scales. Within the E2 individual-weight series from 1 g to 10 kg, it is made of polished special steel that is non-magnetizable, providing a reliable mass reference for quality assurance and routine instrument checks. The knob design supports easy gripping and controlled placement on the weighing pan, while the polished finish contributes to a clean, durable working surface. Net weight is 0,500 kg and gross weight 0,510 kg; the piece is delivered in a plastic box that protects the standard during storage and handling. Manufactured by Sartorius, this knob weight fits analytical, pharmaceutical and general laboratory metrology applications that call for E2-class single weights. Non-magnetizable special steel helps limit magnetic effects that could influence sensitive weighing results. Supplied as one piece in a plastic box, it integrates readily into existing sets of test weights and balance qualification procedures.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 500 g, OIML E2, DAkkS
What is this article?
Knob Weight 500 g, OIML E2, 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.
