I have a cheap amazon pH meter (I think the link is the one I have but I am not sure). It is one of those that comes with 3 calibrations packets each at a different pH. I have calibrated it but the powder in the packet seems to never fully dissolve. I have been looking at getting the hanna pH checker plus to get something more accurate, but I was curious if anyone has ever compared a nicer pH test/meter to one of these cheap ones I have.
Anyone else have experience with the cheap pH meters like this?
