TDS Meter, Digital Water Quality Tester with Automatic Temperature Compensation (ATC), 0-9990 ppm Range, for Drinking Water, Tap Water, Aquariums, Water Filters (Blue)

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.

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.

Great

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

It's really easy to use this device, and it wasn't expensive. It helps me get a better understanding of the water's cleanliness. I wish they made some that could detect plastic, but I realize that sort of goes against how these particular devices work with electricity and what not.

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

Bueno

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 .

Très pratique pour tester l’eau de la ville

Excellent...bought this months ago and still working well.

I purchased this to help me understand my water in and out of my coffee machine. I live in a hard water area, and it helped me to learn about distilling and then making my own coffee water. Easy to use and great build quality. It also looks nicer than similar devices. One note is to make sure any readings are taken at an ambient temperature, if the water is too hot it will read a lot higher than it is, so wait until water has cooled. I discovered this the hard way. I have tested this against another more expensive meter and it gives the same reading, so it appears to be accurate (at least enough for home use).

Accuracy is not the best +/- 50%

I was planning to buy a more expensive product, but I’m glad I didn’t. The one I chose was a great value for the price and turned out to be the right choice. Really happy with the purchase!
