How do I use a TDS meter?

A TDS meter is very easy to use.

1. Firstly, collect water in a clean glass or cup.
2. Turn the power on to the TDS meter, and remove the cap.
3. Insert the 2 electrodes at the end of the TDS meter fully into the water, being sure not to insert the whole unit which could cause damage.
4. Stir the water a little using the TDS meter or shake it slightly to ensure the electrodes are fully immersed, and that no bubbles are attached to the electrodes.
5. Wait about 5 seconds, or until the display stabilises with a constant figure. The figure that you now read is the TDS reading.
6. After you have finished, take the TDS meter out of the water and give it a shake to ensure excess liquid is removed. It is ideal to rinse the electrodes with reverse osmosis water, to ensure that the next test does not contain contamination from the test just completed.
7. Place the cap back onto the TDS meter to protect the electrodes.
