Description
The 1 g OIML M1 calibration weight is an individual scale weight intended for checking and adjusting balances in laboratory and industrial weighing applications. It belongs to the OIML individual scale calibration weights category and is specified in accuracy class M1, making it suitable for routine verification work where this tolerance class is required. Construction is from aluminium, copper, nickel-plated copper or stainless steel, selected according to the nominal mass and class requirements for this weight type. Each piece is supplied in its own protective case to help preserve surface condition and mass stability during storage and transport. Offered by manufacturer Ohaus, this single-piece unit has a net and gross weight of 0,021 kg and is listed under weight class MYD450. It is a practical choice for laboratories, quality-control stations and service teams that maintain balances with traceable reference masses in the low-gram range and need a compact, individually protected 1 g M1 weight for everyday calibration checks.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 1g, OIML M1, OH
What is this article?
Weight, 1g, 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.
