Please for how long can it be use before replacement? I've been using mine for the past 3years..... Do you think the electrode is still good to give accurate pH result?
Why does this black residue form around the probe? I noticed they don't offer a seal with the cap so I keep mine I'm a ziplock to prevent it from evaporating got that figured out but this black residue is crazy? I assume we need the buffer solutions, the storage solutions AND a solution to clean the probe etc? I wish they had a good seal on the cap
Hi 👋 is it still left in the sump and do you need to leave it turned on 👍🏴
Is it already calibrated when I buy it it?

You should recalibrate it
No rinse between 7.01 and 4.01 thats gonna mess with accuracy later?
Do we need to store calliberate solution liquid with us always when use ?
Hi, I don't have calibration button. Only on/off. What should I do?
Store it in rodi and completely clean off solution between calibration and clean in rodi b4 going into tank
