TDS meter

A tds meter is a little tool that helps us to know how clean and safe our water is. You know how we need to drink clean and healthy water to stay healthy, right? Well, water is made up of lots of tiny things that we can't see with our eyes, like minerals and salts. Some of these things we need in our water, but if there are too many of them, it can make us sick.

A tds meter has a little pointy thing at the bottom that we put into the water we want to test. It tells us how many tiny things are in the water that we can't see. If there are too many, it tells us that the water might not be safe to drink or use. If there are just the right amount of tiny things, then it tells us that the water is safe and healthy to drink.

So, in short, a tds meter helps us test how clean and safe our water is by telling us how many tiny things are in the water that we can't see with our eyes.
