Description
Weight set KERN 303-05 is a precision E1 class calibration weight set covering the full range from 1 mg to 500 g. The individual pieces are designed as knob weights and manufactured from polished stainless steel to ensure long-term mass stability and corrosion resistance during repeated laboratory handling. Milligram weights in the 1 mg to 500 mg denomination are supplied in a separate plastic case for clear organisation and protection. The complete assortment is housed in a wooden case that supports secure storage and transport between workstations. This set from manufacturer Kern is intended for verification and adjustment of analytical balances, precision scales and other weighing instruments that require OIML E1 tolerances. With a net weight of 3,2 kg the collection provides a practical selection of reference masses for routine quality-control checks, metrology laboratories and industrial calibration tasks. The polished stainless-steel construction maintains surface integrity while the wooden outer case and dedicated milligram insert keep every piece readily accessible and protected against contamination or mechanical damage in daily professional use.

Questions about Weight Set KERN 303-05
What is this article?
Weight Set KERN 303-05 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.
