[LunRRy]

Is it already calibrated when I buy it it?

Please for how long can it be use before replacement?

I've been using mine for the past Do you think the electrode is still good to give accurate pH result?

[tristiniwanski]

No rinse between 7.01 and 4.01 thats gonna mess with accuracy later?
