Description
Calibration weight 5 mg, OIML class E2 with NVLAP certificate is an individual reference mass intended for accurate balance verification and metrological calibration. The single-piece weight meets or exceeds OIML class E2 tolerances according to OIML R 111 and features a high-gloss, mirror-polished surface that reveals scratches and contaminants at a glance while promoting long-term stability. Approximate dimensions are 4,98 mm width, 4,75 mm depth and 2,39 mm height, with a nominal net mass of 0,005 kg. Delivered as one piece in a high-quality protective case, it remains secure, clean and dust-free in storage and transit, protecting the investment in laboratory precision. Configured as an OIML individual calibration weight without display devices, it supports both routine performance checks and formal calibration of analytical and precision balances in controlled laboratory settings. From manufacturer Ohaus, this NVLAP-certified E2 weight provides a dependable milligram-level standard for laboratories that require documented traceability and consistent reference performance in everyday metrology applications.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight 1P OIML 5mg CLE2 Accrd TR
What is this article?
Weight 1P OIML 5mg CLE2 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.
