Description
Knob weight in OIML E2 accuracy class is an individual calibration weight intended for precise checking and adjustment of balances in laboratory and industrial metrology. Manufactured from special steel with a high-gloss polished finish, it is non-magnetizable and highly corrosion-resistant, with a density of 8,0 g/cm³. The nominal net mass is 0,100 kg, placing this piece in the range where E2 single weights from manufacturer Sartorius are supplied in a wooden case (from 50 g upward; plastic boxes are used up to 20 g). Within the broader E2 individual-weight programme covering 1 g to 50 kg, this knob-style design supports routine verification, intermediate checks and reference work where stable geometry and low magnetic susceptibility matter. The polished special-steel construction aids clean handling and long-term dimensional stability under normal laboratory conditions. Supplied as a single piece, it fits quality systems that rely on traceable test weights for balance control, method validation and day-to-day performance monitoring without introducing magnetic interference or excessive surface wear.
This article is part of Calibration & test weights, in Balances & scales.

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 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?
