Description
Test weight KERN 307-13 is a single OIML class E1 reference weight with a nominal mass of 5 kg. Manufactured from polished stainless steel in knob form, it is intended for high-accuracy verification and calibration of precision balances and scales. The E1 classification ensures the tightest tolerances required for metrological work in laboratories, quality-control departments and accredited calibration facilities. Net and gross weight are both 5,0 kg, reflecting the solid stainless-steel construction. This individual weight from manufacturer Kern provides a stable, corrosion-resistant standard that can be handled conveniently thanks to the knob design. It is supplied as one piece and supports routine checks as well as formal calibration procedures where OIML E1 accuracy is specified. The polished surface facilitates cleaning and long-term dimensional stability under normal laboratory conditions.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Test Weight KERN 307-13
What is this article?
Test Weight KERN 307-13 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.
