Description
The 500 mg OIML E1 wire weight with NVLAP certificate is a high-precision individual calibration weight for demanding laboratory and metrology applications. It belongs to OIML Class E1, offering high accuracy, tight tolerances and a guaranteed uncertainty of one third of the tolerance. Weight surfaces meet or exceed OIML R 111 and are polished to a mirror-smooth high-gloss finish. This single calibration weight from manufacturer Ohaus arrives in a high-quality protective case that maintains the weight in a secure, clean and dust-free condition. The NVLAP calibration certificate is accredited to ISO 17025 and recognised by ILAC, ensuring traceable performance. The weight satisfies or surpasses the tolerances specified for OIML classes E1, E2, F1 and F2. Packaged as 1 pc, the wire form has dimensions of 12,57 mm width, 3,58 mm height and 11,38 mm depth. It is suitable for calibrating analytical balances and precision weighing equipment in research, quality-assurance and industrial laboratories that require dependable reference standards.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight Wire 1P OIML 500mg CLE1 Accrd TR
What is this article?
Weight Wire 1P OIML 500mg 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.
