Description
Wire weight E1 is a high-accuracy individual calibration weight for demanding balance verification in the milligram range. E1 single weights cover 1 mg to 500 mg and are manufactured from non-magnetisable special steel with a density of 8,0 g/cm³ and high corrosion resistance, supporting stable metrological performance under laboratory conditions. The wire construction is practical for small nominal values where compact geometry and controlled surface finish are essential for repeatable placement on balance pans. Delivered as one piece with a net weight of 0,002 kg and gross weight of 0,090 kg, this reference weight from manufacturer Sartorius is supplied in a plastic box for protection during storage and transport between calibration points. It is intended for laboratories, metrology rooms and quality units that require E1-class standards for fine-range checks, adjustment workflows and ongoing monitoring of analytical and micro balances. The non-magnetisable steel helps limit magnetic influences that could affect low-mass readings, while the defined density supports consistent handling characteristics. Use this wire weight wherever traceable, corrosion-resistant E1 references are needed for precise weighing applications.

Questions about Wire Weight 20 mg, OIML E1
What is this article?
Wire Weight 20 mg, OIML E1 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Instruments de laboratoire.
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.
Which category should I open next?
