Description
Test weight KERN 347-13 is a single weight of OIML class M1 with a nominal mass of 5 kg. It features a knob form and is produced from finely turned stainless steel in accordance with OIML requirements. This individual calibration weight is intended for verification and adjustment of balances and scales that operate within M1 tolerance limits. The finely turned stainless-steel surface provides a stable, corrosion-resistant body that retains its mass characteristics under normal laboratory handling. Supplied as one piece, the weight can be used alone or incorporated into existing weight sets for routine checks. Manufactured by Kern, the 347-13 model follows the established geometry and finish expected of OIML M1 knob weights at the 5 kg level. Its robust construction supports repeated use in quality-control and metrology environments where reliable reference masses are essential. The knob design allows secure grip and straightforward placement on weighing pans during calibration sequences. Net and gross mass both correspond to the stated 5 kg nominal value, ensuring the unit itself serves directly as the reference standard without intermediate adapters.

Questions about Test Weight KERN 347-13
What is this article?
Test Weight KERN 347-13 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.
