Description
Test weight KERN 307-03 is a single OIML class E1 calibration weight with a nominal mass of 5 g, manufactured as a polished stainless-steel knob weight. Class E1 accuracy makes the piece suitable for high-precision verification and adjustment of analytical and microbalances in metrology and quality-control laboratories. The knob shape allows secure handling with tweezers or weight forks while minimising surface contamination. Polished stainless steel provides corrosion resistance and long-term mass stability under normal laboratory conditions. Net and gross weights are both listed at 0,05 kg, reflecting the complete packaged unit. This individual test weight from manufacturer Kern supports routine balance checks, intermediate verification and formal calibration workflows that demand the highest OIML tolerance class. Compact packaging dimensions of 0,015 m height by 0,008 m width by 0,008 m depth facilitate organised storage in weight sets or dedicated calibration cabinets. Laboratories performing pharmaceutical, analytical or research weighing benefit from a traceable 5 g E1 reference that maintains its metrological integrity over repeated use. The combination of E1 classification, polished stainless-steel construction and knob geometry delivers a reliable reference standard for precision mass determination.

Questions about Test Weight KERN 307-03
What is this article?
Test Weight KERN 307-03 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.
