Description
Test weight class M1, stainless steel, 50 g ± 3,0 mg is a precision reference mass for routine verification and adjustment of laboratory balances and scales. Fabricated from stainless steel, it combines mechanical robustness with good corrosion resistance for everyday metrology use. The nominal value of 50 g is held within a maximum permissible error of ± 3,0 mg, corresponding to OIML R-111 class M1 recommendations. Net mass is 0,050 kg. An individual protective case is supplied for secure storage and transport; a calibration certificate is not included. This METRIA-type weight from manufacturer Labbox is intended for quality-control laboratories, production weighing stations and teaching environments that require a dependable M1-class standard without accompanying certification paperwork. Supplied as a single piece, it supports periodic balance checks, comparative weighing exercises and instrument qualification workflows where stainless-steel M1 masses are specified. Clear class marking and the included case help maintain traceability of the physical standard between uses.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Precision weight, stainless steel, class M1, 50 g ± 3,0 mg
What is this article?
Precision weight, stainless steel, class M1, 50 g ± 3,0 mg is the article on this page. Luminix Health distributes Labbox 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.
