I plan to buy Pinpoint ph monitor w/probe. I do not know how reliable and accurate it is . Can anyone tell me the advantage and disadvantage of the monitor?
Mine is about 2 yrs old and I have no complaints. It does need to be calibrated now and then, which can be a bit of a chore. I do it every time the battery needs replacing, which is every 2-3 months at a guess.
Based on comparing readings with chemical tests, it is very accurate.
