Description
Weight set KERN 303-09 is a complete E1 accuracy class calibration weight set covering the full range from 1 mg to 10 kg. Individual weights are produced in knob form from polished stainless steel, providing stable reference masses for precision laboratory and metrology work. The milligram weights in the subdivision 1 mg to 500 mg are housed in a separate plastic case, ensuring organised handling and surface protection. The entire assortment is presented in a wooden case that safeguards the polished finishes during storage and transport. Offered by manufacturer Kern, this set supports verification and calibration of high-accuracy balances where E1-class tolerances are required. The polished stainless steel construction combines corrosion resistance with long-term dimensional stability under normal laboratory conditions. Supplied as one complete set, the collection is suited to quality-control laboratories, calibration services and analytical facilities that need traceable reference masses. The wooden outer case together with the dedicated milligram insert keeps every piece secure and readily accessible for routine use.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Weight Set KERN 303-09
What is this article?
Weight Set KERN 303-09 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.
