The 5 mg OIML E1 wire weight is an individual calibration weight developed for high-accuracy laboratory and metrology applications that demand the lowest possible tolerances. OIML Class E1 guarantees elevated precision, reduced tolerance bands and an uncertainty limited to one-third of the tolerance. Weight surfaces satisfy or exceed OIML R 111 criteria and are polished to a mirror-smooth high-gloss finish that facilitates clean handling and long service life. Although Troemner Alloy 8 stainless steel—with its strictly controlled density of 8,03 g/cm³, extremely low magnetic characteristics, excellent stability and corrosion resistance—is designated for the 1 g–20 kg series, this wire weight extends the same class performance into the low-milligram range. Manufacturer Ohaus supplies the weight in a high-quality case that ensures secure, clean and dust-free storage, protecting the user’s investment. The single calibration weights meet or surpass the tolerances defined for OIML classes E1, E2, F1 and F2. Measuring 4,98 mm in width, 2,39 mm in height and 4,75 mm in depth at a nominal mass of 5 mg, the piece is ideal for calibrating precision balances. Pack size is one piece.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight Wire 1P OIML 5mg CLE1 NoCert TR
What is this article?
Weight Wire 1P OIML 5mg CLE1 NoCert TR is the article on this page. Luminix Health distributes Ohaus for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Instrumenten.
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?
