Description
Weight, 5 kg, OIML M3 is an individual scale calibration weight intended for verification and routine calibration of laboratory and industrial balances. This OIML class M3 mass standard is manufactured from stainless steel and supplied in a protective sleeve that helps preserve surface integrity during handling, storage and transport. The nominal value of 5 kg makes it a practical reference for mid-range weighing systems, while the net weight of 5,214 kg characterises the complete unit. Suitable for quality-control checks, service workshops and metrology tasks where class M3 tolerances are specified, the weight supports consistent instrument performance without requiring higher-accuracy fine weights. Produced by Ohaus, it belongs to the range of OIML individual scale calibration weights covering nominal values from 1 g to 10 kg, all fabricated from stainless steel and delivered with protective packaging. The robust construction provides corrosion resistance and long-term dimensional stability under normal laboratory conditions. Packaged as a single piece, this calibration weight offers a straightforward physical reference mass for maintaining the accuracy of weighing instruments according to OIML recommendations in daily laboratory and industrial use.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 5kg, OIML M3, OH
What is this article?
Weight, 5kg, 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.
