TDS Meter Reverse Osmosis Reef Water PPM Tester PT-TDS1

What does the tester do?

The electronic water tester displays the amount of total dissolved (TDS) in water.

How does it work?

It's easy! With the push of a button, the electrodes in the bottom of the tester measure the amount of ions in the water and convert that amount to a number which displays on the screen.

What does the number mean?

The number represents the amount of parts per million, or milligrams per liter, of dissolved solids that exist in your water sample. The higher the TDS reading the higher the amount of dissolved solids in the water.

Why is this important to me?
The tester will empower you to be able to evaluate the cleanliness of whatever water you're drinking...bottled, tap, filtered, etc. The cleanest water will show a reading of "000". <20ppm was acceptable for drinking.
