YSI delivers the sensor ready for operation. The electrolyte solution
and the membrane head must only be replaced:
 the membrane is heavily contaminated and a calibration error
occurs
(log book message)
 the membrane is damaged
(log book message)
 the electrolyte solution is depleted or the counter electrode is
poisoned
(log book message)
 after the gold working electrode and the silver counter electrode

Caution
The ELY/A electrolyte solution irritates eyes, skin and mucus
membranes. If it comes into contact with the eyes, rinse
thoroughly with water and consult a doctor! During working
activities, always wear suitable protective gloves and protective
goggles/face shield! Follow the safety datasheet.
