Description
Weight 20 g, OIML M1 is an individual scale calibration weight intended for accurate verification and adjustment of laboratory balances. Built to OIML M1 accuracy class requirements, this single-piece reference mass supports consistent checks of analytical and precision balances in quality-control and metrology settings. Depending on the nominal value, construction uses aluminium, copper, nickel-plated copper or stainless steel; each weight is supplied in its own protective case to protect the surface finish and preserve metrological performance. Available from manufacturer Ohaus, the unit is practical for routine bench-top calibration work in pharmaceutical, research and industrial laboratories. Net and gross weight are both 0,063 kg, accounting for the mass and its individual packaging. The product is categorised as an OIML individual scale calibration weight and contains no display devices, functioning purely as a physical reference standard. Well suited to laboratories that rely on robust OIML M1 single weights for regular balance performance verification and internal quality systems.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 20g, OIML M1, OH
What is this article?
Weight, 20g, OIML M1, OH 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.
