Perfect for saving money By Paul on 10/22/2014

I use this TDS meter on my inlet, after my RO membrane, and after my DI cartridges. It works perfect for multiple reasons. First, I know what my TDS coming in and going out of my RO membrane so I can tell if I'm getting the rejection I should and know when it's time to replace my membrane. Next, when I first turn the unit on, I can flush the good water coming out of the membrane until the TDS comes down so I'm not using up resin. This is from TDS creep, read about it if you haven't heard of it. Lastly, it tells me when I need to change my resin as the last one will show me if TDS comes above 0, so I'll know the resin is exhausted. Perfect and not a big investment.

It is great being able to monitor 3 stages of filtration By mfief on 6/26/2014

Being able to monitor the TDS after the carbon blocks, ro unit, and after the DI resin is great. No need for un necessary filter changes. You can check three phases of filtration in seconds and replace only the necessary filters. This will save money in the long run.
