Description
The 1 mg OIML E1 wire calibration weight provides high accuracy with low tolerances and a guaranteed uncertainty of one-third of the tolerance. Surfaces meet or exceed OIML R 111 and are finished to a mirror-smooth high-gloss polish. This individual calibration weight meets or exceeds the tolerances of OIML classes E1, E2, F1 and F2. Supplied from manufacturer Ohaus in a high-quality protective case, the weight stays safe, clean and dust-free during storage and handling. The accompanying NVLAP calibration certificate is accredited to ISO 17025 and recognised by ILAC. With a width of 4,11 mm, height of 1,52 mm and depth of 3,66 mm, the compact wire form supports precise metrology work. Designed as an OIML individual calibration weight, it serves laboratory balance verification, quality-control routines and high-resolution weighing systems that demand Class E1 performance. Offered as a single piece, the weight delivers a stable reference standard for analytical and precision applications in controlled environments where tight tolerance and low magnetic influence are essential.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight Wire 1P OIML 1mg CLE1 Accrd TR
What is this article?
Weight Wire 1P OIML 1mg CLE1 Accrd TR is the article on this page. Luminix Health distributes Ohaus 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.
Which category should I open next?
