DON'T MAKE WATER WITHOUT ONE!! By jason on 11/27/13jason would recommend this product to a friendIF 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 11/24/13Frank would recommend this product to a friendI 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 11/23/13Jason would recommend this product to a friendI 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 11/21/13James wouldn't recommend this product to a friendI 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 11/8/13Sven would recommend this product to a friendNot 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
good and easy to use By k35 on 10/14/13k35 would recommend this product to a friendworks well and easy to hook into the system
Well worth the investment By Charlie on 10/6/13Charlie would recommend this product to a friendIt 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 9/29/13Matthew would recommend this product to a friendI 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.
Works just as described By Trojan on 9/22/13Trojan would recommend this product to a friendThere was a little confusion until I looked at the video from brs.
