Description
Weight Set OIML 500 g–1 mg Class E1 Accredited TR is a precision OIML calibration weight set containing 24 individual weights covering the range from 1 mg to 500 g. These adjusted weights meet or exceed the tolerances specified for OIML classes E1, E2, F1 and F2 and are delivered to Class E1 with NVLAP accreditation, ensuring high metrological traceability. The set is intended for laboratory calibration of analytical balances and precision weighing instruments where fine mass increments are required. Supplied as one complete set from manufacturer Ohaus, it offers a net weight of 1,11 kg and a gross weight of 3,402 kg. Packaging dimensions are 0,2413 m depth, 0,18606 m width and 0,1143 m height, corresponding to a volume of 0,005 m³. Manufactured in the USA and designated as an OIML Calibration Weight Set, the product includes no display devices and concentrates on pure reference masses. This twenty-four-piece kit is suitable for accredited laboratories performing detailed mass metrology and balance verification tasks at Class E1 level.

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