Great convenience but leak problem By Steve D on 7/10/2013Steve D would recommend this product to a friendThis is a great item to have, but it has a rigid plastic 1/4-inch probe section that fits into the supplied T-fitting. But it has a slow leak between the rigid plastic insert and the quick-lock fitting which caused me to have to put a ball valve in my input water supply just to turn it off between uses so that my otherwise dripless RO system and connectors wouldn't drip, drip, drip day and night.
water quality By Billy on 5/30/2013Billy would recommend this product to a friendNever tested my ro system. Since I just bought the upgrade and booster pump from 75 gallon to 150 gallon. I had to get some way to see my water quality. Worth every penny.
Excellent! By Loren on 4/22/2013Loren would recommend this product to a friendHooked it up out of the box, was getting a reading instantly. Great for letting you know when you need to replace your filters, so in a sense saves you money. And keeps your aquarium clean and in tip top shape. I will not go with out one anymore.
A needed item if you have a RO/DI system By Rob Coberg on 12/3/2012Rob Coberg would recommend this product to a friendI order one of these units a week or so ago, good thing I did . I would have never known my tds were hi as they were. I am taking corrective action to get it to 0 tds where it should be.

Works great. Best way to determine if RO/DI system is ok By Tony on 6/5/2012Tony would recommend this product to a friendThe Single Inline TDS meter does a great job of detecting TDS in my RO/DI system. I use it once every two weeks to monitor for need for filter change. Easy on/easy off. Great price.
Use it anywhere By John on 4/26/2012John would recommend this product to a friendI put this meter in front of my RO unit to monitor the TDS of my well water. When I see it going up I know it's time to do a little home maintenance. Handy meter for sure
