The sensor spots have a rough green
sensing surface. Their backside is green
smooth and shiny, and adheres on the
adhesive side of the packaging (on which
the sensor code is printed on the outside).
The sensor spots can be glued with their
backside
on transparent,
clean and dry
inner
container walls (plastic or glass, wall thickness
0-6 mm) using an appropriate adhesive, like e.g. transparent
silicone based on acetic acid (item no.
SPGLUE
). After the glue has
dried, the gas or liquid sample has to be filled into the container so
that the rough green sensing surface of the spot is completely
covered and in contact with the sample.
For containers with
wall thicknesses of 0-2 mm
, the
Basic Spot Adapter
(a 10x10x10 mm plastic cube,
item no.
SPADBAS
) needs to be fixed tightly or
glued to the outer container wall at the spot
position. Then the sensor signal can be read out
using the
Optical Fiber
(item no.
SPFIB
or the
bare-fiber-version
SPFIB-BARE
) connecting the
basic spot adapter with the
FireStingO2
.
For measurements through containers with
wall thicknesses of 2-
6 mm
, the metallic
Lens Spot Adapter
(item no.
SPADLNS
) with an integrated collimating lens has
to be used instead. It comes together with a flexible
re-adjustable cable binder for quick positioning of spot adapters
e.g. on laboratory flasks with a maximal diameter of ~10 cm.
Please note, that the
Lens Spot Adapter
does
not work when submersed in water, because the
integrated lens is working properly only in the
gas phase. The spot adapter is then connected
with the
Optical Fiber
(item no.
SPFIB
,
SPFIB-
BARE
) to one channel of the
FireStingO2
.
