Water can be contaminated with a variety of pollutants, including bacteria, viruses, chemicals, metals, and radionuclides. Food is often tested for hygiene and safety, but this level of control isn't always that accurate when it comes to drinking water. Whether it comes from the tap at home or served to us in a restaurant, we usually assume that clean water is safe if it looks good, tastes and smells good. Neither of these three factors is a measure of purity, however.
Lishtot TestDrop Pro, tests your drinking water in two seconds
This gadget of the company Lishtot performs a simple test to see if your "clear" water is actually good to drink.
How does it work? Water emits its own local electromagnetic field, which TestDrop Pro analyzes. The TestDrop Pro uses the electromagnetic reading to determine if the water is safe to drink. Pure water produces a slightly different reading than water containing lead, chlorine, or E. coli. The TestDrop Pro can test for the presence of up to 20 pollutants, and does not need to be placed in water to perform the test.
How is the portable drinking water test done?
Tests with Lishtot can be run repeatedly without any latency. The device is so small that it can be adapted to any keychain: three simple buttons allow you to perform an analysis for as many types of water (tap water, bottled water, still water).
Because? Although all are waters considered safe to drink, they have some crucial differences in their composition.
It goes without saying that the companion app on the smartphone cannot be missing, which is used to keep track of all the tests carried out. The device only gives an "ok" with a small green light (good water to drink) or red (do everything with it, but don't drink it): the app can obviously provide more information about water.
In some cases and scenarios it can be a life saver, or at least a "stomach saver": if you want more information you can find it at this address (It is not a sponsorship, nor a paid review. I have not even received samples of the product. Nothing. All spontaneous).
