Très pratique pour tester l’eau de la ville

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.

No complaints. It does what it’s suppose to do.

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%
