Description
Knob weight M2 is an individual calibration weight intended for general-purpose balance checks and routine metrology tasks. It forms part of the M2 single-weight range from 1 g to 10 kg and is manufactured from fine-turned brass. Depending on nominal value, smaller pieces up to 20 g are delivered in a plastic box, while weights from 50 g upwards are supplied in a wooden case. This unit has a net weight of 0,500 kg and a gross weight of 0,530 kg, making it suitable for everyday verification where class M2 accuracy is sufficient. Fine-turned brass provides a stable, workable surface for laboratory, workshop and production environments that need dependable test masses without ultra-high precision classes. Supplied as 1 pc from manufacturer Sartorius, the weight integrates easily into existing calibration sets and quality-control procedures. The graded packaging protects the mass during storage and transport while keeping the knob-weight format convenient for manual placement on balance pans during adjustment and performance checks.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Knob Weight 500 g, OIML M2
What is this article?
Knob Weight 500 g, 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.
