Does anyone have the older model dissolved O2 probe where you have to change the electrolyte solution? I've never used them before and have been tasked with trying to get some to work. I need to replace the polarograhpic solution but the instructions are scant and I am not sure where I put the fluid? Anyone use them and can shed some light on the subject?

Hi linotas If you look on the ciderhouse tech website they have clips for each sensor showing how to calibraite and maintain them. hope this helps

Yeah I did but this is the older style one and they only have their newer, optical one.
