DeFelsko PosiTector SST Quick Guide

t = test duration
T
2
= sample temperature
∆
γ
= The change in conductivity. The
initial background measurement (
γ
1
)
is automatically subtracted from the
final measurement (
γ
2
) Test results
are displayed in units of microsiemens
per centimeter (conductivity).
ρ
A
=The surface density of soluble
salt expressed as sodium chloride.
Test results are displayed in units of
milligrams per square meter, or
micrograms per square centimeter.
If a memory batch is open, the measurement result will be stored
in memory (pg. 9).
e) Press the (+) button to begin a new test.
Patch Removal
The Bresle Method DeFelsko Patch peels off the surface easier
and with less residue than conventional Bresle patches. Remove it
immediately after the test and dispose.
The Bresle Method PosiPatch lifts
cleanly off the surface, with absolutely
no residue. The user may choose to
discard the PosiPatch and begin the
next test with a new one, or simply
rinse it with DI water and reuse for
several more tests until worn.
Rinsing the Test Cell
Rinse the test cell with unused DI water
several times after each measurement,
shaking the water out after each rinse.
