Usefull TDS Meter By Mark on 9/29/2014

I have this meter testing the water coming out of my membrane as well as the water coming out of my DI resin. It is very accurate and helpful. When the time comes where it need to be calibrated, the price point is good enough to purchase another.
Helps to take the guess work out By Travis on 8/19/2014
Travis would recommend this product to a friend
Very easy to install and even move around if you are wondering what each area is doing. Changed mine over to the discharge side just to see what flushing does and I will tell you that it is a good idea to flush your RO before and after each use it does help. I only have about 190 TDS going in but while I'm flushing I have seen over 400 TDS coming out. This is a must have for anyone with an RO/DI unit.

I'm only giving this a 4 because the directions for installing it were lacking. Once I got it hooked up it seems to be working well. Definitely need to have one on your filter.

You need this. Takes the guesswork out of filter replacement. Really simple to install and operate. Very nice for the price.

How Can You Not Have One By Austin on 4/19/2014

how do you know what your system is doing are you at 0 TDS? the dual meter tells you what is going in to your DI canister and what is coming out. No more Hoping my RO/DI unit is working right.
Must have item on RO/DI system By Rick on 4/18/2014
Rick would recommend this product to a friend
This meter is a great addition to any system. Much easier then a pen type checker. To have confidence in the water going into your tank you need to know if the filter is running as it should be. With this you will know in seconds.
Why didn't I have one when I started!? By TriggerThis on 4/13/2014

A must have!
I didn't have one, almost crashed my tank putting 30TDS top off water in it every day because I didn't know my DI was exhauseted.
Don't have to worry any more
Literally takes 6 seconds to install
WORKS WELL UNTIL CALIBRATION IS NEEDED By NONE on 4/10/2014

GOOD LUCK CALIBRATING FOR THE AVERAGE JOE. AT THIS POINT IMO IT BECOMES DISPOSABLE. FOR THE PRICE AND GETTING SEVERAL YEARS USE IT IS WHAT IT IS.
put a few on your rodi system By Chicago on 3/25/2014
Chicago would recommend this product to a friend
I love these things. I use two of them on my system. Use for
1. supply water going in
2. water after the pre filters and after carbon
3. after the reverse membrane but beofre the di cartridges
4 last one after the di cartridges to let me know how the final water is.
so easy and great to monitor.
This works really well By Bob on 3/3/2014

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.
Must have for a rodi system By nicholas on 2/9/2014

I have one of these on my rodi unit now that i thought was reading incorrect but come to find out i got a build a unit from BRS and my first rodi unit didn't work correctly and now it reads right where it should. this definatly saved my tanks from utter distruction

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.

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
Frank would recommend this product to a friend
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
Jason would recommend this product to a friend
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

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
