Description
Weight set KERN 303-056 is a compact E1 class calibration weight set covering 1 mg to 500 g. The knob weights are produced from polished stainless steel, combining excellent corrosion resistance with the mass stability required for demanding metrology work. Milligram weights from 1 mg to 500 mg are stored in a separate plastic case for convenient access and protection of the finest pieces. The complete collection is supplied in an aluminium case that provides a lightweight yet durable enclosure suitable for laboratory benches and field calibration kits. This set from manufacturer Kern is designed for verification and adjustment of high-resolution balances and precision scales that operate under OIML E1 tolerances. With a net weight of 1,6 kg the assortment remains portable while still offering a full range of reference masses for quality control, research and industrial calibration routines. Polished stainless-steel surfaces maintain long-term accuracy, and the aluminium outer case together with the dedicated milligram insert ensures organised, contamination-free storage between uses.

Questions about Weight Set KERN 303-056
What is this article?
Weight Set KERN 303-056 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.
