Hooked this up to my older RO unit and was able to see how well the membrane is performing. Its especially amazing to see the difference between the input and output.
Great addition By Manfred on 2/18/2014

Another way to determine when filter changes are needed. You can see the sediment filter and when it gets dirty. You can see the color change in the DI filter but this meter goes beyond that and confirms numerically what you see actually. Just another RODI precautionary measure.
Great Feedback for RO Membrane By Steve on 2/13/2014

I had no idea whether my RO membrane was ready for replacement before installing this TDS meter. It allows you to monitor the performance of the membrane.

These seem to work very well. One came on my BRS 5-stage RODI system. It had one line of display missing so they sent me a new one asap. It's great to be able to see your incoming TDS and outgoing TDS on the RODI system.

I have been thinking about getting one of these for a long time. I wish I hadn't waited. Takes guesswork out of filter changes. So easy to install.

DON'T MAKE WATER WITHOUT ONE!! By jason on 11/27/2013

IF YOU USE RODI WATER FOR YOUR TANK THEN THERE IS NO EXCUSE TO NOT HAVE A TDS METER. THIS ONE IS AFFORDABLE AND VERY ACCURATE AND LETS ME KNOW MY WATER QUALITY COMING IN AND GOING OUT. SUPERB.....
Great, especially with membrane flush kit By Frank on 11/23/2013

I really like this Dual TDS Meter. I watch my TDS drop every time I turn on my RO unit and flush the membrane. I use one after the di resin to let me know when that is exhausted too.
A must for your RO/DI system By Jason on 11/23/2013

I added one of these TDS meters to my system about 4 years ago. It gives a good reading of your before/after water. If you are looking for the cleanest water for your reef, I'd recommend adding this to your water source and keeping an eye on it.
not accurate By James on 11/21/2013

I have this installed on several systems and its very far off the mark. You can try and calibrate yourself but it will only change a few PPM and its much further off than that
The more you know the better By Sven on 11/7/2013

Not only are my 2 Dual Inline TDS meter's reading the same parameters, but I would never have realized that you need to flush the clean side of your membrane before making water without these!
I was always told just to flush your waste line... But my post Membrane Product line is around 180ppm when I first start.. After about 30 seconds of flushing the clean product line I am down to 4ppm.. I can flush my waste lane for 5 minutes and not see it drop below 100ppm... No wonder I was going through so much DI Resin

It is very important to me to know that my RODI unit is working 100% this TDS meter works perfectly, it feels good to know that the water entering is at 233 TDS and is exiting at 0. Now I will know what to change my filter media
Worked Great, needed Replacement, Works Great Again By Matthew on 9/29/2013

I got one with my BRS 5 STage RO/DI unit and after a couple months is stopped working correctly. I contacted BRS and they shipped me a replacement. It was easy to install and replace. I wouldnt run and RODI without one. 4 stars bc the first one failed.

Cool product that is both useful and fun. Will help you replace filters at the right time. And it's fun to see how crappy your water coming in really is, and just how clean the water coming out is. Spend the extra $5 and get the dual unit.

Worked for about 5 days then just stopped turning on. Piece of junk product or just a lemon, but I am not happy.
