EASY BREEZY By MICHAELO on 9/30/13MICHAELO would recommend this product to a friendGreat product, turn it on and place it in the water to be tested. Works like a charm. I take it places and use it to show people what their water has in it, and when it's not RO/DI woooooooo there are all kinds of numbers! Have fun and a piece of mind when adding water to your tanks!

HM TDS Meter w/temp By MadMatt on 3/24/13MadMatt would recommend this product to a friend
This is very easy to use ....I just received the meter
today. I ordered it on the 21st and it showed up
3 days later !! NOT BAD!! I live in Alaska.
This meter is great. I ordered their pH meter as well
last year and no problems or issues on that meter.
The TDS meter comes factory calibrated and was very close only one point off. I will order the same thing should this one come up missing !!!!
A one year old can work this By Thao on 2/1/13Thao would recommend this product to a friendSo easy to use that a kid can effortlessly test the TDS of your water. I have an inline TDS meter also and they read the same. I like to portability of this product because I use it to test water for other people who don't have one. Product seems to be made of nice material also.
great meter - add to your essential tookit By Paul on 1/2/13Paul would recommend this product to a friendAccurate, fast & easy to use. I've compared this with my inline digital TDS meter on my RO/DI unit, & it's right on the mark. Comes with a nice carry case.
Great portable TDS meter By Nick on 12/4/12Nick would recommend this product to a friendIt's great having a TDS meter built into your RO/DI system, but having a portable model to check your ATO reservoir and other bins that store RO water is essential. This device fits the bill. Minus one star for only displaying Celsius. :)
best bang for the buck By mikey on 8/15/12mikey would recommend this product to a friendgreat portable tds meter. calibrated straight out of the box so no need to mess around with calibration fluids. love having the piece of mind knowing my ro unit is working flawlessly. also a great fun factor testing water around the house.
Very simple! By Jordan on 6/9/12Jordan would recommend this product to a friendWorks like a charm. Take out of the case (already factory calibrated) and just dip it in some water and you have a very quick and accurate reading!
Great Tds By Jeff on 6/1/12Jeff would recommend this product to a friendThis is a great Tds and at a great price easy to use and compared to a friends very high end meter it is dead on and at a very small fraction of the price
Great product. By Gerardo on 5/25/12Gerardo would recommend this product to a friendVery easy to use, fast and accurate reading.
A Must Have! By Terry on 5/25/12Terry would recommend this product to a friendIt's shocking to see the lack of quality of water that you actually pay for. I have fun testing different bottled water sources then compare them to the water my RODI puts out! This is a must have!
Works Great, Easy to use. By Keith on 5/11/12Keith would recommend this product to a friendAll you have to do is dunk and press a button after 10 seconds. It is very easy and light weight but doesn't feel flimsy or delicate. Used it for a month now and no sign of it slowing down. Piece of mind for 22$ that my RODI machine is doing it's job. Plus it's fun to test the other water sources as well.
