  • Very simple and accurate
All you have to do is put this inside of a glass of water and it'll give you the measurements of your TDS in your water. For the price it works fine.

  • Works well for my RO water supply
I purchased a small RO water filter with a DI polisher so I use this to make sure that I’m getting pure water out of my system/ Easy to read with a green backlight, results are very repeatable, can’t verify accuracy since I have nothing to measure it against.

  • Mostly accurate. Easy to use and nice features.
I work in a field where we work on reverse osmosis machines and was wanting something just for just a quick and dirty check not for official calibrations or maintenance. This is actually decently accurate on the low end 0-20uS/ppm. Mine was only off by 1uS. Not as accurate on the high side. It was off by almost 50 at 300uS. This was versus a really expensive calibrated meter. I havent had a chance to use calibration solution to check it yet. I will probably try 10 and 100uS and see how it does. ... show more

  • Good quality for TDS
Nice and unexpected leather storage sleeve. Measuring is easy and accurate.

  • Easy to use
Bought to check my ro water system so I would know when to have filters changed. Works great.

  • Average water meter
There is a chart on the back of the meter when you turn it on it is green. When you sample the water it will turn red most of the time but when you use a distiller to clean the water it turns green with the ppm at a 3 or higher but not the same range as on the scale. I'm not sure how to get the water to a blue as it dtate that is the ideal drinking water. ... show more

  • The Good, the Bad, & the Ugly!
Wow, first I tested a brand new bottle of drinking water from the store. It only read 4 parts per million of contaminates, very good 👍. Then I tested the water coming outta the faucet in my travel trailer I live in, in an county park. I had also just replaced the inline filter that morning, and it still failed miserably as expected. It read in at 567ppm of contaminates, well into the red zone. Any reading over 500 can make you extremely ill. I'm gonna say this little gauge is working very well. Worth every penny. ... show more

  • Just what I needed!
In red is the sink water and green is the distilled water. Works great and easy to use and clean!
