I did not have a tds meter installed to my RODI system when first starting out with my reef tank. After 4-5 months of excellent water parameters I suddenly had a huge phosphate spike. After realizing the problem was my RODI filters expiring I added this meter and never looked back. Excellent and very important tool.
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

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 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

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.

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.

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.
