I bought this because I had a problem with my RODI water. After installing I verified the problem and replaced my DI cannister and resin. It is very easy to install and nice that you can continually moniter all three stages.

Great product does the job nicely and very accurate. I was very disappointed to find that there were no 3 way connectors included and I had to run out to buy my own although they did give a $10 refund for forgetting them.

Came with 3 t-fittings but all 3 are incorrect, the probes do not fully seat into the fitting, have to be able to see probes thru the fitting, but don’t go deep enough. Cannot use until I get proper fittings that allow the probes to seat properly

TLDR: This RO/DI system kit is a breeze to install and offers precise TDS readings that match handheld meters. It comes with all necessary fittings, allowing for easy integration into existing water systems.I installed this kit on my RO/DI system to monitor water quality more effectively. The kit was designed for various water lines, including raw water, post-RO, and finished RO/DI. The installation was straightforward; the kit included all the fittings needed, so I just had to cut my existing water lines at the desired measurement points and insert the connectors with sensors.The accuracy of the TDS readings from this kit is impressive, consistently matching those from my handheld meter. This ensures reliable and precise monitoring of water quality. Integrating this kit into my system has made the process of maintaining optimal water conditions much simpler and more efficient.

The product was packaged good. It feels really good. I bought this since brs ro/di systems come with this brand. I hooked it up correctly. Line 1 water coming in, line 2 waste water, line 3 purified water coming out. I'm getting 70 on line 1, 35 on line 2, 0 on line 3. Line 1 and two must be backwards. You can't have less tds coming out of the membrane than going in. It is working correctly and I'm assuming it's correct. If the lines weren't switched I would give this 5 stars.

If u don't like throwing out money then u must buy this, I was changing ro filters every 6 months until I got this and confirmed it wasn't even needed and now only need to do it every year

ACHTUNG! - das Ding ist NICHT für MEERWASSER Aquarium geeignet!! In der Beschreibung steht das nirgendwo!Der Verkäufer unterdrückt wohl absichtlich den Hinweis um mehr Umsatz zu machen - unseriös, denn alle anderen Verkäufer klären den Käufer auf das Einsatzfeld auf.Jetzt liegen zwei solche Dinge im Abfall, weil ich vor Jahren schon mal reingefallen bin.AUFPASSEN !!!
