Description
Test weight KERN 307-11 is a single calibration weight of nominal mass 1 kg manufactured to OIML class E1. The weight is formed as a knob weight and finished in polished stainless steel, giving the surface quality expected for precision metrology work. OIML class E1 represents the highest accuracy tier routinely used for calibrating analytical balances and reference standards in accredited laboratories. Polished stainless-steel construction resists corrosion and simplifies cleaning, supporting long-term mass stability under repeated handling. Supplied as one piece with a net weight of 1,00 kg, this individual weight is suitable for routine verification and adjustment of high-resolution weighing instruments in laboratory and quality-control environments. The unit forms part of the KERN test-weight programme from manufacturer Kern and provides a compact, corrosion-resistant mass standard for professional calibration tasks where traceable OIML E1 performance is required.

Questions about Test Weight KERN 307-11
What is this article?
Test Weight KERN 307-11 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.
