Description
Knob weight M2 is a single test weight for checking balances and scales within the M2 accuracy class. With a nominal mass of 2 kg, it is made from finely turned brass and belongs to the M2 single-weight range from 1 g to 10 kg. According to the series design, pieces up to 20 g are packed in a plastic box, while weights from 50 g upwards—including this 2 kg unit—are supplied in a wooden case for secure storage and transport. Finely turned brass provides a defined surface suitable for routine laboratory and industrial verification tasks where M2 tolerances apply. Use this knob weight for periodic instrument checks, intermediate controls and straightforward mass comparison on the bench. The individual weight is available from manufacturer Sartorius as a single piece for quality-control and service applications. Net weight is 2,000 kg and gross weight with packaging is 2,320 kg. The wooden case protects the knob weight during handling and helps maintain the working surface between calibration or verification sessions in the laboratory environment.

Questions about Knob Weight 2 kg, OIML M2, DAkkS
What is this article?
Knob Weight 2 kg, OIML M2, 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.
