Description
E1 knob weight is a high-accuracy individual calibration weight designed for precision metrology and the verification of analytical and microbalances. It forms part of the E1 single-weight series spanning 1 g to 50 kg and is produced from special steel that is high-gloss polished, non-magnetizable and highly corrosion-resistant, with a stated density of 8,0 g/cm³. These material properties support long-term mass stability and low magnetic susceptibility, which are essential when working at the E1 tolerance level. The weight is supplied as a single piece; in this product family, pieces up to 20 g are housed in a plastic box and pieces from 50 g upward in a wooden case. Net weight is 0,700 kg and gross weight 0,980 kg, reflecting the robust protective packaging typical of precision reference masses. Ideal for accredited laboratories, calibration services and quality systems that require top-tier OIML E1 performance, this knob weight from manufacturer Sartorius provides a durable, corrosion-resistant reference for demanding weighing applications.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 500 g, OIML E1, DAkkS
What is this article?
Knob Weight 500 g, 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.
