General Information
Designed for high voltage porosity detection, PoroTest®
7 conforms to the following industrial standards:
DIN 55670
DIN 50191 (VDE 0104)
DIN EN 61010 /Teil 1 (VDE 0411/ Part 1)
1.1
Applications
PoroTest® 7 holiday detector detects pores and holes
in insulating materials on conductive substrates such
as steel, aluminum, etc. Typical applications: Testing
linings and coatings applied on ducts, pipes, hulls, oil
and storage tanks , enamel, paint, rubber and bitumen
linings, vessels and tanks, GFK and other plastics
materials.Tanks or vessels must be filled with water or
other conductive material. To detect porosity, the
appropriate test voltage specific to the material thickness
is set on the control unit which applies, when activated,
a spark discharge at the moment a material flaw is
detected. In addition to the spark discharge, flaws are
counted and indicated by a visible and audible signal.
Depending on the test electrode, test voltage can be set
from 0.5...7 kV (P7) for coatings from 30 microns to
1.7mm or from 6 to 35kV (P35) for coatings from 1.4mm
to 11,3mm.
