TDS meters are often used in laboratories and by water treatment plants, but these tools can be just as useful for the average homeowner who wants to know what’s in their water. Here is everything you need to know about TDS meters – what they do, how to use them, and when it might be smart to get one for yourself.

What is TDS?
TDS stands for total dissolved solids. These are minerals, salts, metals, etc. in water that can be harmful if they reach too high of a concentration. These meters measure the amount of these solids in the water when the water is in contact with the electrodes inside the probe.
How do TDS meters work?
TDS meters are essentially pH monitors, but instead of measuring whether the water is acid or basic, it measures how many minerals and ions there are in the water. A small chip inside the meter responds to minerals passing by. The total number of minerals dissolved in the water will change the pH of the chip. The meter then calculates the TDS by measuring how much the water has changed the pH of this chemical bath and displays it on a digital screen.
How to use a TDS meter?
Using a TDS meter is very simple. Simply submerge the probe under water and wait around 30 seconds. While you are waiting, you might be wondering how this device can measure mineral content in minute traces if it takes so long to get an accurate reading – well, the answer is that it is measuring the water as a whole and only small amounts of minerals pass through. If you want to get an exact reading you need to wait longer.
Tips for using your new TDS meter
- Check if your meter needs batteries or plugs in.
- Some meters use a single probe while others have multiple – check to see what you need when shopping around.
- Know what kind of substances you are testing for before using your TDS meter – Some meters take a few seconds, others a minute or more – know what will work best for you.
- Learn about your meter before using it to get the most out of it.
Frequently Asked Questions on TDS Meters
What do TDS meters measure?
TDS meters measure the conductivity of water by taking into account all dissolved particles in the water. Conductivity is proportional with TDS, hence why TDS meters are used to estimate total dissolved solids.
How accurate are TDS meter readings?
TDS meter readings are very accurate if used correctly. The TDS meter is actually measuring the salinity of the solution which is covered by two different measurements – conductivity and resistivity. Resistivity has more to do with mineral solubility than salinity (i.e., it measures how easily currents can pass through a solution). Although both conductivity and resistivity are affected by salinity, the TDS meter reading is really a measure of conductivity.
Can TDS meter measures pH in water?
A TDS meter cannot directly measure pH. The function of a TDS meter is to measure the total dissolved solids in a solution and thus it can be used to approximate pH by measuring the resistance (or impedance) of the solution. A higher TDS reading correlates with a lower solution pH (i.e., more acidic), whereas a lower TDS reading corresponds with a higher solution pH (i.e., more basic).
How to calibrate a TDS meter?
You can calibrate TDS meter by adding 5 ppm of KCl(Potassium Chloride) solution to the probe. This is a common procedure for almost all TDS meters where you have to add a certain amount of solution and then calibrate it. When you add KCl the meter will show lower values than actual and when you add distilled water it will show higher.
Where to buy a TDS meter locally?
You can access local shops to buy a TDS meter. It is not convenient though because you have to travel long distances just to purchase what you need. To be able to save time, energy, and effort, it is now possible to buy online using the internet. You can easily search for sites that sell testing meters over the net.
Conclusion
The above-listed TDS meters could be used as a preliminary testing tool for assessing the quality of water followed by detailed testing through a recognized water testing lab which could potentially find out other harmful chemicals present in the water thereby helping you decide whether you really need a water purifier or not.
As mentioned above, some of the TDS measuring instruments are really cheap and available at a very low price which you can buy online. These instruments are fairly accurate and do make use of these TDS checking machine/device to check the level of TDS in water.
