Description
Test weight KERN 318-03 is a precision milligram calibration weight of OIML accuracy class E2 with a nominal mass of 5 mg, formed as a polished stainless-steel leaf (Plättchen). It is intended for verification, adjustment and routine performance checks of analytical and microbalances in pharmaceutical, chemical, quality-control and research laboratories. The E2 class supports metrological work where fine mass standards are required under controlled ambient conditions, helping laboratories confirm weighing accuracy as part of internal calibration programmes and quality-management systems. The compact leaf geometry allows secure placement on the balance pan while limiting handling contact with the working surface. Finished in polished stainless steel, the piece offers a stable, durable surface suitable for repeated laboratory use. This single-piece milligram weight from manufacturer Kern is supplied ready for professional metrology applications and fits workflows that rely on discrete OIML-class reference masses for balance qualification, intermediate checks and documented verification of high-resolution weighing instruments across regulated and research environments.

Questions about Test Weight KERN 318-03
What is this article?
Test Weight KERN 318-03 is the article on this page. Luminix Health distributes Kern 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.
Which category should I open next?
