P
OLAROGRAPHIC PROBE
Unscrew the probe's head and the membrane
permeable to oxygen.
If necessary, replace the membrane.
Fill the probe's head with the DO 9701 electrolyte
solution until the level indicated in the figure
(filling level).
Eliminate any possible air bubble in the electrolyte
solution.
Screw the probe's head back on carefully.
G
ALVANIC PROBE
1.
Unscrew the probe's head and the membrane permeable to oxygen. If necessary, replace the
membrane.
2.
Attach the needle to a 10 ml syringe.
3.
Using the syringe, withdraw the DO 9701.1 electrolyte solution.
4.
Remove the air bubbles inside the syringe. Insert the needle into one of the
four holes surrounding the cathode of the probe and inject the solution until it
leaks out. The fill volume is approximately 5 ml.
5.
Screw the probe's head back on carefully.
After replacement of the electrolyte solution and/or membrane, insert the probe's connector in the
instrument and wait 15 minutes before performing the dissolved oxygen measurement (this is the
necessary time to exhaust the oxygen trapped in the electrolyte solution during the replacement).
