Description
Knob weight M2 is a single test weight intended for calibration and verification tasks on laboratory and industrial weighing instruments. It forms part of the M2 individual-weight series from 1 g to 10 kg and is made of finely turned brass for a precise, workmanlike finish. According to the series specification, pieces up to 20 g are supplied in a plastic box and pieces from 50 g upwards in a wooden case; this unit has a net weight of 0,200 kg and a gross weight of 0,500 kg including packaging. The knob design allows secure handling and stable placement on the balance pan during routine checks. M2-class weights are widely applied in quality control, service and production environments where dependable working standards are needed. Finely turned brass offers good durability for day-to-day metrology use. This single weight from manufacturer Sartorius originates from Germany and fits established calibration workflows. Supplied as one piece per pack, it can be used alone or combined with other reference masses for balance testing and instrument performance verification.

Questions about Knob Weight 100 g, OIML M2, DAkkS
What is this article?
Knob Weight 100 g, 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.
