Description
The 20 g OIML M3 calibration weight is an individual scale calibration weight intended for checking and adjusting balances in laboratory and industrial environments. Manufactured from stainless steel, it belongs to the OIML accuracy class M3 and forms part of the range of single weights covering nominal values from 1 g to 10 kg. Each piece is supplied in a protective cover that helps shield the surface during storage and transport, supporting consistent performance over repeated use. This compact calibration weight from manufacturer Ohaus is suitable for routine verification of weighing instruments where M3-class tolerances are specified. With a net weight of 0,063 kg it is easy to handle on the bench while remaining stable on the pan. Typical applications include quality-control checks, periodic balance testing and metrological confirmation in research, production and service laboratories. The single-piece format allows targeted calibration of specific weighing ranges without the need for a full weight set, making it a practical addition to any calibration toolkit that relies on OIML-compliant reference masses.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 20g, OIML M3, OH
What is this article?
Weight, 20g, OIML M3, 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.
