Description
The 500 g OIML M3 calibration weight is an individual scale calibration weight used for verifying and adjusting the performance of balances and scales in laboratory and industrial settings. Constructed from stainless steel, it meets the requirements of OIML accuracy class M3 and arrives in a protective cover that helps preserve surface integrity during transport and storage. Weights ranging from 1 g to 10 kg share this stainless-steel design and protective packaging from manufacturer Ohaus. The unit has a nominal mass of 500 g, with both net and gross weight specified as 0,582 kg, making it a compact reference standard for routine metrological checks. It features no display devices, confirming its function as a pure physical mass standard. Quality-control laboratories, production facilities and service technicians rely on such M3 class weights for periodic calibration of weighing instruments according to established procedures. Supplied as a single piece, this calibration weight supports consistent accuracy verification workflows without unnecessary complexity.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight, 500g, OIML M3, OH
What is this article?
Weight, 500g, 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.
Which category should I open next?
