Description
1 g OIML M3 calibration weight is an individual scale calibration weight for verifying and adjusting precision balances and scales in laboratory and quality-control environments. It forms part of the OIML Individual Scale Calibration Weights range and is specified to OIML accuracy class M3, supporting routine calibration and metrological verification tasks at the gram level. Weights from 1 g to 10 kg in this series are manufactured from stainless steel and are supplied in a protective sleeve that helps safeguard the surface during storage and handling. Scientific specifications indicate a net weight of 0,021 kg and a gross weight of 0,021 kg; the product is delivered as a single piece without integrated display devices. Available from manufacturer Ohaus, this compact test weight is practical for calibration benches, analytical laboratories and production areas that require class M3 mass standards for periodic instrument checks. Stainless-steel construction together with the individual protective sleeve facilitates clean handling and organised storage in professional weighing workflows where small, standardised calibration masses are essential.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 1g, OIML M3, OH
What is this article?
Weight, 1g, 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 Instruments de laboratoire.
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.
