Description
Knob weight F2 is a single test weight for calibration and verification of balances and scales in laboratory and industrial metrology. It belongs to the F2 single-weight range covering 1 g to 10 kg and is produced from special steel that is finely ground and non-magnetizable, giving a stable, low-interference mass standard for routine checks. The knob form allows secure handling with tweezers or weight forks while protecting the load face. Each piece is supplied in a plastic box that shields the surface during storage and transport between workstations. Net weight is 0,050 kg; gross weight including packaging is 0,090 kg, so the unit remains easy to move on the bench. This calibration accessory from manufacturer Sartorius supports quality systems that specify F2 class individual weights for periodic instrument control, service, and incoming inspection. The finely finished, non-magnetic construction helps maintain consistent weighing behaviour under normal laboratory conditions. Suitable for metrology labs, production QA, and service technicians who need durable single knob weights for balance verification workflows.

Questions about Knob Weight 50 g, OIML F2
What is this article?
Knob Weight 50 g, OIML F2 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.
