Description
Calibration weight 5 g, OIML class M3, is an individual scale calibration weight intended for verification and adjustment of laboratory and industrial balances. Fabricated from stainless steel and supplied in a protective case, the weight is shielded from contamination, corrosion and mechanical wear that could affect its mass value. The OIML M3 classification delivers the tolerance band appropriate for routine calibration work where class F or E reference standards are not required. Offered as a single piece with a nominal mass of 5 g and a net weight of 0,126 kg, the unit is easy to place and remove from the balance pan. This stainless-steel calibration weight from manufacturer Ohaus is part of a uniform series spanning 1 g to 10 kg, all produced to the same material specification and packaging standard. Common applications encompass periodic checks of precision balances, process-control weighing stations and educational laboratories that adhere to OIML recommendations. Swiss origin together with the certificate confirms the declared accuracy class and supports traceability documentation.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 5g, OIML M3, OH, CERT
What is this article?
Weight, 5g, 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.
