Description
Test weight class E2, stainless steel, 500 g ± 0,8 mg is a precision reference mass for verifying and adjusting laboratory balances that require high-accuracy calibration. The nominal mass of 500 g is realised in stainless steel with a stated tolerance of ± 0,8 mg, aligned with the recommendations of OIML R-111 for class E2 weights. An individual protective case is included to support orderly storage and transport between calibration sessions; a certificate is not included with the weight. This single-piece unit is intended for routine balance checks, quality-control workflows and instrument qualification where a stable class E2 reference is specified. Net weight is 0,500 kg, matching the nominal value for straightforward handling on the balance pan. The stainless steel body offers a durable, corrosion-resistant surface suitable for clean laboratory environments. Offered as a METRIA-type test weight from manufacturer Labbox, it integrates easily into existing calibration sets or standalone verification tasks. Laboratories can use it for periodic performance confirmation of analytical and precision balances without expanding inventory beyond the required 500 g class E2 point.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Precision weight, stainless steel, class E2, 500 g ± 0,8 mg
What is this article?
Precision weight, stainless steel, class E2, 500 g ± 0,8 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.
