Hello,

I observe the same symptoms than Gilles.
I observed it on 2hours + dives on multiple days of diving
I do the first calibration on the boat, with air out of a scuba tank and O2 out of my onboard O2 using a "flow reducer type" calibration kit like most MEG divers I ve seen.
My sensors face definitely got wet after the first dive and I couldn t get a decent pO2 reading (doubting my flushes at the beginning but no, nothing did, I got only a 1.4-1.5 max).
I do not doubt my calibration at all either as I got proper readings with dil flushes at the beginning of 1st dive.
I recalibrate with wet sensors and then no pb.
I noticed that my Mv readings dropped quite a bit over the trip (down to 40-45Mv instead of 45-50), probably because of this oisture on the sensors
I still recalibrated every day of the trip as sensors remained wet and only CCR diver so I was not sure about my cells getting "used" a bit too fast or if it was coming from this moisture or both together.
