Description
OIML weight set 1 mg–500 mg Class E1 Accredited TR is a precision calibration weight set comprising 12 adjusted weights that meet or exceed the tolerances of OIML classes E1, E2, F1 and F2. Intended for high-accuracy laboratory and metrology applications, the set covers the range from 1 mg to 500 mg and carries NVLAP accreditation for traceable calibration work. Supplied as one complete set, it serves as a reliable reference standard for verifying analytical balances and precision weighing instruments in quality-control and research environments. The product type is listed as OIML Calibration Weight Sets, with a net weight of 0,00111 kg and a gross weight of 0,681 kg. Packaging measures 0,2413 m depth by 0,12065 m width by 0,12065 m height and occupies 0,004 m³. These weights from manufacturer Ohaus support rigorous calibration routines where Class E1 performance and documented traceability are required, ensuring consistent results across accredited laboratories.

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