Does anybody know of a good TDS Ph meter combo? Or even two really good individual items? I was looking for some but looking at the contradicting reviews, it is hard to make a good decision. Anybody have any insight for me

item number 121010758851 for ph, item number 270730169264 for tds meter.
on eBay.

the key for a good meter is to calibrate it once a month.

Some pH meters require calibration prior to every use, so keep that in mind. It's why so many people stick with liquid tests.

As far as TDS meters go, you can get great ones for about $10 shipped on eBay.
