Description
Test weight class F1, stainless steel, 20 g ± 0,25 mg is a precision reference mass intended for verification and adjustment of laboratory balances. Manufactured in stainless steel to accuracy class F1, it complies with the recommendations of OIML R-111 and offers a nominal mass of 20 g with a maximum permissible error of ± 0,25 mg. The single-piece unit is delivered with an individual protective case for secure storage and contamination-free handling during routine calibration work. Net mass is 0,020 kg. Belonging to the METRIA product type from manufacturer Labbox, this test weight supports everyday metrology tasks in analytical, industrial and teaching laboratories; a certificate is not included with the delivery. Stainless-steel construction provides good resistance to corrosion and helps preserve mass stability under typical laboratory conditions, giving users a practical OIML-aligned F1 standard for periodic performance checks on precision and analytical weighing instruments.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Precision weight, stainless steel, class F1, 20 g ± 0,25 mg
What is this article?
Precision weight, stainless steel, class F1, 20 g ± 0,25 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.
