D-D TDS Tester Meter & Digital ThermometerA TDS Meter measures the amount of Total Dissolved Solids (TDS) in a solution. Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution which is then converted to a TDS reading. TDS is directly related to quality of water i. e., the lower a TDS figure, the more pure the water. As an example, reverse osmosis purified water will have a TDS between 0 and 10,

Good value
I like how it comes with the magnet mount as well as a sticky backed metal piece to use. It has a nice weight to it too, it doesn’t feel cheap.

Get this for your coffee bar
Perfect for your grounded coffee. I attached this to my ninja machine, and this was so good. It is out available for next use. No problems with it falling down.

High Quality
This tool has very nice weight (all metal) and very nice machined finish. Feels very premium without the premium price. Well thought out with the magnetic base or 3m double sided tape included. Nice that they included replacement needles. Would definitely buy again.

Works great and is affordable!
Color: Black
Works great! The magnet it comes with is quite weak. But the tool itself works great.
