The Lishtot TestDrop Pro, Better Than a TDS Meter
TDS meters measure the concentration of Total Dissolved Solids in a solution.
They were made popular by water filter manufacturers who use TDS meters to convince consumers their filters are working by demonstrating how the TDS reading goes down once the water is filtered.
But what do TDS meters actually tell us about water safety and quality?
The simple answer, according to the NSF, is NOTHING at all.
TDS meters are good at one thing: testing for minerals. But they cannot distinguish between 'good' minerals that are meant to be in water (such as calcium, sodium, and magnesium) and 'bad' minerals that are actual contaminants. Also, TDS meters cannot test for other contaminants such as heavy metals like lead, copper, arsenic, and cadmium.
Enter the TestDrop Pro, the next generation of TDS meters.
The TestDrop Pro is the first personal water tester that actually tests for contamination instead of just minerals. Plus, it can distinguish between those 'good' and 'bad' minerals.
When you test with the TestDrop Pro, you are testing your water for actual harmful contaminants like Lead, Copper, Arsenic, bacteria (including E. coli), and many other types of chemicals and organic substances.
