Description
The 100 mg OIML F1 calibration weight is an individual precision mass standard for verifying and adjusting laboratory balances and comparable weighing instruments. As an OIML individual calibration weight it is specified to meet or exceed OIML class F1 tolerances, making it suitable for routine calibration and performance checks in analytical laboratories and quality-assurance settings. Surfaces comply with or exceed OIML R 111 and present a high-gloss, mirror-like polish so that scratches or contamination remain clearly visible, supporting stability and durability in daily use. The weight is delivered in a high-quality case that protects it from dust, impact and handling damage, helping preserve accuracy between calibrations. Approximate dimensions are 9,75 mm width, 3,3 mm height and 9,75 mm depth, a compact form factor well matched to fine-range balance work. Offered by manufacturer Ohaus within its OIML individual calibration weight range, this 100 mg F1 piece supports metrology tasks that demand reliable class F1 performance. Origin is the USA, and the product is supplied as a single piece for dedicated laboratory calibration applications.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight 1P OIML 100mg CLF1 No Cert TR
What is this article?
Weight 1P OIML 100mg CLF1 No Cert 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.
