The consideration of diaphragm ( probe head
with diaphragm set ) :
The oxygen probe component is the thin Teflon
diaphragm housed in the tip of the probe. The
diaphragm is permeable by the oxygen molecules but
not by the considerably larger molecules contained in
the electrolyte. Due to this characteristic, the oxygen
may diffuse throughout the electrolyte solution
contained in the probe, and its concentration may be
quantified by the measurement circuit.
This sensitive diaphragm is rather delicate & is easily
damaged if it comes into contact with solid objects or is
subjected to blows. If the diaphragm is damaged or the
electrolyte is run out, it must be replaced in the following
way :
Probe-filling Electrolyte,
OXEL-03
Probe head with diaphragm set
1)Unscrew the " Probe head " ( 7-3, Fig 5 ).
2)Pour out the old Electrolyte from the
container of the " Probe head ".
3)Fill the new Electrolyte ( OXEL-03 )
into the container of the " Probe
head " .
