Excellent TDS Monitor
There is no reason not to give this product the highest rating. The price was right, it does exactly what it is supposed to do and it is easy to install. The meter is simple to install; I have mine mounted with clamps right onto the side of the RO gland. Simply push the button for power and select, back and forth if you wish, the input water TDS or the output water reading. The display is easy to read and it turns off by itself. I personally like to stay in the habit of manually turning off equipment when not needed. I checked it with a professional meter and the readings were identical. It is so convenient to use, allowing frequent checks that will keep the water quality up. Don't be surprised, it is smaller than one would expect, but not a problem, its still easy to read from an arms length.

Easy to install, works like a charm.
I could hardly believe how easy this instrument was to install. It must have taken me at least two minutes and it was up and running producing accurate results, I checked it with my handheld meter. The display is a little small but that's no big thing. Pun intended.😀 a great buy in my opinion.

Very convenient to test my water.
I love this tds in line meter. I always know when I need to change my water filters now. It came with everything I needed to hook it up to my aquaticlife RO water lines. It gives a tds reading of the water before and after it runs through my RO filter.

Easy to install
easy to install, easy to read. Only thing is, it would be nice to have a backlight and an option to plug it in to an outlet rather than batteries.

Easy and accurate
Easy to hook up took 5 min tops. Have one probe on waste water and the other after the DI media. Takes the guess work out of when to change DI media!
