whats a good one to buy. i know i gave my old one away. it was a hanna one. i dont like the inline one from the rodi unit because they are not accurate.
Been using one of those $20 baby blue ones for 3 years now, zero problems and it's accurate. Pretty sure tds meters are one of the few things where the el cheapo ones are good enough.

+1 I have the same baby blue one too. I don't even remember what brand it is. I calibrate it every so often and it has not let me down. Then again my inline tds has been spot on for over 3 years. I just use the other to double check from time to time. So I guess any digital tds meter will work. Just buy the calibration fluid with it.
I have a Hanna TDS1 (baby blue) for sale. Hardly used, but needs new batteries. It has an on/off switch and I forgot to turn it off one too many times. $10. PM me if anyone is interested.
