DeFelsko PosiTector SST Manual De Instrucciones página 2

The PosiTector Soluble Salt Tester (SST) is a hand-held
electronic instrument that measures the conductivity of a solution
and calculates the concentration of water-soluble salts on metal
surfaces in accordance with ISO 8502-6 (the Bresle Method) and
ISO 8502-9. It consists of a PosiTector body (Standard or
Advanced) and an interchangeable probe.
The PosiTector SST is compatible with all Bresle Method-type
patches including the Bresle Method DeFelsko PosiPatch, Bresle
Method DeFelsko Patch and other adhesive patches. While
compatible with any test patch, there are numerous advantages to
the DeFelsko patch solutions.
The Bresle Method DeFelsko Patch is low cost,
latex-free, and works on nearly any surface
geometry or material. It features a low-tack
adhesive which creates a tight seal while
remaining easy to remove without leaving behind
any foam residue.
The Bresle Method DeFelsko PosiPatch further
simplifies the Bresle method. It requires no
adhesive, as it is held to a steel surface by a
magnetic holding ring. It has a built-in port which
allows deionized (DI) water to be injected using a
dull polypropylene dispensing tube, eliminating sharp needles
from the test. It features a patented air-permeable membrane,
which automatically releases trapped air as DI water is injected,
then allows air bubbles to return and agitate the surface as
solution is withdrawn. It is also reusable, and a single PosiPatch
can be used for multiple tests.
The PosiTector SST can be used as a conventional conductivity
meter making it ideal for testing abrasive materials in accordance
with ISO 11127-6 and ASTM D4940-15. See Bresle Mode (pg.
10).
