Description
Knob weight 1 kg (class M1) is a single test weight designed for calibration and checking of balances and scales in laboratory and industrial settings. It forms part of the M1 single-weight series covering 1 g to 10 kg and is manufactured from galvanised brass, offering a robust, corrosion-resistant mass standard in classic knob form for convenient handling. The individual 1 kg weight is delivered in a plastic box that protects the surface during storage and transport between verification tasks. Net weight is 1,000 kg and gross weight is 1,050 kg for the packed unit of 1 pc. This knob weight from manufacturer Sartorius supports routine M1-class calibration work in quality control, teaching laboratories and production weighing stations where galvanised brass construction is preferred. The knob design allows secure placement and removal on the weighing pan, while the protective plastic case keeps the reference mass clean and ready for repeated use. Suitable for facilities that require a durable M1 single weight for external checking and adjustment of laboratory balances.

Questions about Knob Weight 1 kg, OIML M1
What is this article?
Knob Weight 1 kg, OIML M1 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.
