oxygen towards the 3 mm tip has a measurable effect on the
response time. For optimum operation conditions it is therefore
recommended to utilize these robust probes in permanently stirred
liquids (this diffusion limitation is negligible in gaseous samples;
see also the respective sensor specifications).
Ensure that the complete sensing surface of the
Robust Oxygen
Probe
is covered completely by the sample and prevent
mechanical stress (e.g. scratching) to the sensing surface!

Sensor Spots
PyroScience
offers a
range of
contactless
oxygen
sensors
,
comprising
sensor
spots,
respiration
vials
and
flow-
through cells. The
sensor
spots
are
coated
with
the
REDFLASH
indicator
with PET foil or glass
as carrier material.
The sensor spots allow oxygen measurements in closed vessels in
combination with the
FireStingO2
equipped with
Optical Fibers
(e.g. item no.
SPFIB
or
SPFIB-CL2
). The sensor spots have
standard diameters of 5 mm (item no.
OXSP5
) and can be
optionally obtained with an optical isolation (black coating) on the
sensing surface (e.g. item no.
OXSP5OI
,
OXSG8OI
). Optical
isolation is recommended if strong illumination
might disturb the measurement or if no light shall
be introduced into the sample.
