Description
Weight 5 g, OIML M1 is an individual scale calibration weight intended for routine verification and adjustment of laboratory balances. Manufactured to OIML M1 accuracy class, this single-piece reference mass supports reliable checks of analytical and precision weighing instruments in quality-control and metrology environments. Depending on the nominal value, the weight is produced from aluminium, copper, nickel-plated copper or stainless steel and is delivered in an individual protective case that helps preserve surface condition and metrological integrity between uses. Supplied by manufacturer Ohaus, the compact unit is suited to bench-top calibration workflows in pharmaceutical, research and industrial laboratories. Net and gross weight are both 0,025 kg, reflecting the small format and protective packaging. The product belongs to the OIML individual scale calibration weights category and is free of display devices, making it a straightforward physical reference standard. Ideal for laboratories that require durable, class-M1 single weights for periodic balance performance verification and internal quality systems.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 5g, OIML M1, OH
What is this article?
Weight, 5g, 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 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.
