Description
Knob weight 1,4 kg (class M2) is a single test weight for calibration and functional checking of balances and scales in laboratory and workshop environments. It belongs to the M2 single-weight range from 1 g to 10 kg and is made from finely turned brass, providing a stable mass body in traditional knob geometry for easy handling on the weighing pan. According to the series specification, pieces up to 20 g are supplied in a plastic box and pieces from 50 g upward in a wooden case; this 1,4 kg unit is therefore presented in the wooden case format for secure storage. Net weight is 1,400 kg and gross weight is 1,500 kg for the packed unit of 1 pc. This knob weight from manufacturer Sartorius is appropriate for routine M2-class verification tasks in quality control, educational labs and production areas that specify finely turned brass reference masses. The knob form supports controlled placement during adjustment procedures, while the protective case helps preserve surface finish between uses. A practical choice wherever a durable M2 single weight is needed for external balance checking.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 1 kg, OIML M2
What is this article?
Knob Weight 1 kg, OIML M2 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.
