I'm looking for some good (cheap) pH meter which could be connected to PC, or which can save its measurements to memory in set intervals. Please, do you have some tips? I want to measure (log) pH in my aquarium each hour for 1 or 2 days ... to see how the pH changes during the day and night.
So far I have found "Hanna pH Turtle" (HI-9815) for about ₤70 ($100), but it seems that this product ended/finished.
Thanks for your tips.
