Permi is a new on-line
paper quality analyzer, designed for monitoring
grades where porosity is a critical variable.
Permi provides continuous and immediate feedback
on quality and changes of porosity. The measurement
time is one millisecond (1 ms) with even low porous
papers. The analyser can be used in machines producing
the following grades: sack, cigarette, filter,
MG-kraft, bank note, photo, SC, LWC base, saturating,
tissue, coping etc. papers.
Because of the new design there are no dead times
in measurements as it is in the case of conventional
analyzers. The analyser meets the needs of ISO
5636-1, ISO 5636-2, ISO 5636-3, ISO 5636-4 standards
as well as the most frequently used units as Bendtsen,
Schopper, Gurley, Borgwald, Coresta etc can be
used when presenting results.
