SENSOR STORAGE
If long-term storage of probes is required, empty electrolyte out of probe leaving only a little solution on
the membrane to keep it wet. Leaving a full volume of electrolyte in DO probe long-term without use will
deplete the probes’ anode. See section “Sensor RE-CONDITIONING ” for steps on how to open and close
probe housing.
