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

Works well and super fast reading

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!

Works an absolute dream!!! - seems accurate as used it against my digital RO TDS meter and may even exactly!!! Nice an compact also

Got this to test my RO water, works well tap water was 105 ppm waste from RO was 175 ppm RO water was 005 ppm. Okay it's probably not the most accurate piece of kit but gives me a good idea of my water quality.

Very good, easy to set up and use

I would have expected a guide to be with the instructions, like a range of good to poor.

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).

Works well zero tds on RO water and the aquarium about 210 ppm handy to know when filters need doing on an Ro water system

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.

Accuracy is not the best +/- 50%

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
