A TDS meter is a small hand-held device used to indicate the Total Dissolved Solids in a solution, usually water. Since dissolved ionized solids, such as salts and minerals, increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that reading.

TDS meters have gained significant popularity in recent years. People have realized that they are some of the easiest tools to use when it comes to checking the purity of water. As more and more people take their health seriously, it is only expected that TDS meters will be found in every single home just like light bulbs and fans. So, why are they becoming so popular when there are some ingenious methods of cleaning the water available? Here are some benefits of using TDS meters that should help you make up your mind to buy one.
