Description
The 20 g OIML class M3 calibration weight is an individual scale calibration weight intended for verification and adjustment of laboratory and industrial balances. Produced from stainless steel, it is supplied in a protective case that shields the surface from damage and contamination during handling and storage. Calibration weights in the 1 g to 10 kg range share this stainless-steel construction and protective housing from manufacturer Ohaus. Classified to OIML accuracy class M3 and certified, the 20 g nominal mass supports applications that require documented compliance with this tolerance class. Typical uses include routine performance checks of precision balances, quality-assurance protocols, production weighing and metrology workshops. The single-piece unit has a net weight of 0,163 kg and a gross weight of 0,163 kg, and originates from Switzerland. Its robust finish and compact form allow repeated use while preserving the defined mass value, providing a practical reference standard for laboratories operating under OIML M3 requirements. The protective case also simplifies organised storage and safe transport alongside other calibration masses.

Questions about Weight, 20g, OIML M3, OH, CERT
What is this article?
Weight, 20g, OIML M3, OH, CERT is the article on this page. Luminix Health distributes Ohaus 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.
