Any suggestions for a TDS Meter....or 3?

[Reefer_Madness]

I'd like to get at least a couple of TDS Meters for my RODI system.  One before, one before the resin, and one at the end.  I see that some of the meters have 3 sensors, but they cost about the same as 3 individuals. 

 

Is there a certain brand anyone has had good luck with?

Get two of the below. "Make and offer" of $25. I did and they auto except it. Got it in and no problems. I use two of the below on my RO/DI system so I can check the health of the membrane and DI resin.
