Description
Protective working cover KERN PES-A04S05 is a multi-pack of laboratory balance covers for keyboard and housing protection on compatible precision balances. The set contains five covers, giving laboratories spare units for rotation, replacement, or multi-instrument benches. Each cover helps limit dust, spills, and routine contamination on controls and casing during daily weighing work. Net weight is 0,05 kg with a gross weight of 0,10 kg for the packed set. These protective working hoods from manufacturer Kern are specified for precision balances of the PES and PEJ series and are not suitable for PES 31000-1M. Supplying five pieces in one pack simplifies stocking for quality-control, analytical, and production environments that keep spare covers on hand. Compact packaging supports efficient storage and shipping. Operators can fit a cover quickly for protection during use and remove it when unrestricted keyboard access is needed, helping maintain cleaner instruments and more consistent laboratory hygiene around the weighing station.

Questions about Protective Working Cover KERN PES-A04S05
What is this article?
Protective Working Cover KERN PES-A04S05 is the article on this page. Luminix Health distributes KERN for laboratory use. It sits in Balance accessories, calibration & certificates, inside Balances & scales, in Instruments de laboratoire.
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.
