TDS meter?

[marki24]

so I have been thinking of getting a TDS meter but there are so many out there, I dont know which one to look at. Does anyone recommend any that they have. Are the handheld ones any good? Thanks.

I have the HM digital dm-1 dual tds meter from thatfishplace.com for about $30. I think that is the best price!

I used to have the same one but it got messed up after a couple years. I was somewhat disappointed b/c I hardly used it. (Used to test RO/DI output to determine when to change the membrane)

Here is one, tough I am not familiar with the seller. This is the standard type that many here use.

I now have an HM digital in-line meter. Nice to have if your ro/di unit is connected in a single location
