Description
Test weight class E2, stainless steel, 20 g ± 0,08 mg is a precision calibration mass for verifying and adjusting high-accuracy laboratory balances. Fabricated from stainless steel, it combines dimensional stability with corrosion resistance suited to controlled weighing environments. The nominal mass of 20 g is held within a maximum permissible error of ± 0,08 mg, in line with the recommendations of OIML R-111 for class E2 reference standards. An individual protective case is included to preserve surface finish during storage and handling; a calibration certificate is not supplied with the unit. This METRIA-series weight from manufacturer Labbox supports routine performance checks, intermediate verification and quality-system documentation in analytical laboratories, pharmaceutical QC and metrology workshops. Offered as a single piece with a net mass of 0,020 kg, the compact body is intended for careful handling with tweezers or gloves to avoid contamination. Laboratories that maintain traceable mass standards can integrate this E2 weight into daily balance-control programmes where repeatable, low-tolerance reference masses are required.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Precision weight, stainless steel, class E2, 20 g ± 0,08 mg
What is this article?
Precision weight, stainless steel, class E2, 20 g ± 0,08 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.
