What Is a TDS Meter and How to Use It?

If you have been searching for ways to make water cleaner and safer for you and your family, you must have heard about TDS meters. There are many different ways that use to make water cleaner for them. Filtration remains one of the most common ones. However, there is always this doubt as to how effective the filters really are. At times you are not even sure if your filters are even working properly and the water that you are drinking is safe. That’s when TDS can really help you remove the doubts from your mind.

What Exactly Is TDS Meter?

It is an easy to use tool that helps you know the amount of total dissolved solids by measuring the conductivity of water. It gives you an easy reading that informs you the amount of solids dissolved in water on a part per million basis. In the recent years TDS meters have become quite popular for how easy they are to use and their usefulness. If you have not heard about them before, they are just tools that inform you about the purity and quality of water. Do not expect them to be a tool that cleans water and makes it pure like filters.

How to Use a TDS Meter?

Using a TDS meter is no rocket science. In fact, it might actually be easier to use than a thermometer. Here are the steps you have to follow to use the meter:

  • Put water that you want to test in a cup or container.
  • There will be an on/off switch on your meter. Press the button to turn it on.
  • The electrodes of the meter – the side that will surely have a cap on it – needs to be inserted in the water. You don’t have to insert the whole thing into water. Just like a thermometer, only the metal side needs to go in the water.
  • If you notice bubbles forming on the electrodes, it would best to stir it in the water like a spoon or just shake the container you have the water in. Bubbles can cause inaccurate readings.
  • Keep looking at the LCD of your meter for a stable reading to appear on it. It should not take more than 5 to 10 seconds for the final reading to appear.
  • Note down the reading just in case you forget later. If your meter has this feature, save the reading to view it later.
  • Turn off the meter or simply let it be if your meter has an automatic turn on/ turn off feature.
  • Remove the meter from the water and clean it. Use osmosis water in order to clean it properly and get accurate readings the next time.
  • Do not forget to put the cap back on the meter to keep it from getting damaged.

It is best that you take the TDS readings of two containers: one with filtered water and other with unfiltered tap water. If you don’t notice any difference in the readings, your meter might not be working properly.
