Consistently reproducible results pre and post filtration
I used a Brita water filter for a while. I became concerned that the filters were not working. I switched to Culligan and using these, found the water quality was 102-120 pre-filter and 0-1 after filter. They reduce PFOS and PFOA which is more important to me than sediment. I'm a scientist and rely on instruments like this. It is very easy to use, is a great value to me. I find the results reproducible and believe the accuracy is good. I would buy again.

Accurate Meter
Currently working well for testing water quality coming from my reverse osmosis system. Purchased two different testers to get accurate measurements and this one is about 1 percent different from the other meter which is acceptable.

PPM meter
This PPM meter works great….it’s limited to 999ppm so anything over 999ppm will need another meter….also it’s not backlit which is a common feature…..I’m not sure if it turns itself off when not in use because I gave it away

Works
I have an expensive water system in my house and I was shown how to test for safe drinking water. I purchased this monitor as recommended and it works as well as my water companies. I have actually shown several of my friends how bad their drinking water is which they did not believe until they saw my results and they have a cheap filtering system. Most tap water here in the US is actually not safe to drink unless you have a really high grade filtering system which is worth every Penney .

It works~
It works! We have tested our own running water from the facet and the zero water we make and it shows the difference.

Innacurate
Not accurate. Not sure if I got a faulty meter, but the readings constantly changes while testing the same water. I test the water several times and everytime i get a different reading.

Quality product
Does exactly as described, enabling me to chk when water filter isn't cleaning lime scale sufficiently, when it's passed lot of water and becomes saturated, saving having to change still working filter cartridge prematurely, saving money and the planet!

Not the best for testing drinking water.
Accuracy is not the best +/- 50%
