Questions about Protective Working Cover KERN EWJ-A04
What is this article?
Protective Working Cover KERN EWJ-A04 is the article on this page. Luminix Health distributes KERN for laboratory use. It sits in Balance accessories, calibration & certificates, inside Balances & scales, in Lab instruments.
These are the draft shields, the pans, the ionisers, the printers and the calibration certificates that belong to a balance. A certificate states the errors found at stated loads. It does not make a different balance correct.
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.
