4 Best Tds Meters for Drinking Water

Many people use TDS meters to test the water purity of their drinking water. They help tell the presence of any solids in the drinking water. Tds meters do this by measuring the electrical conductivity of the drinking water. Conductivity in the water indicates the presence of solids.

Tds meters are crucial considering we have diverse sources of water. These little machines can be used in hydroponic systems to measure the salt content and help check the contamination of home water purifier systems. They can also be suitable for commercial filtration systems.

This post will talk about the meters that are available in the market. We’ll also share some of the crucial factors that you should consider before purchasing a Tds meter for drinking water. Keep reading to learn more.

To give you more versatility, many of these meters feature multiple functions. It can include tasks for checking electrical conductivity, temperature, TDS, and PH levels of a water sample.

Always look out for these functions when purchasing these meters to ensure your drinking water is free of impurities.

Secondary Ranges

If you notice your TDS meter has any of the functions discussed earlier, you can opt to check the range of secondary functions. In this case, you can find ranges like PH range 0 to 14, temperature range 32.0 to 176 faranoids, and more.

FAQs About TDS Meters for Drinking Water

What Are the Best Tds Level for Drinking Water?

The best TDS level for drinking water should be between 50-150 ppm. If the TDS levels are high, let us say 1000 ppm, then the water is considered to be unfit and unsafe for human consumption.

What Is a Tds Meter and Why Do You Need One?

A TDS meter is equipment that helps to measure the total dissolved solids in a solution. In many cases, this solution is water.

The conductivity of a solution can change as a result of dissolved ionized solids that include minerals and salts and this can only be measured by use of a TDS meter. The value recorded by the TDS meter has an accuracy of about plus and minus two.

Does Boiling Water Reduce Tds?

You might be wondering whether boiling water can reduce TDS. Well, boiling water does not in any way affect the total dissolved solids of your tap water. The toxic metals present won’t vaporize making them stay in the water. This generally makes the water unfit and unsafe for consumption.

How Can I Remove Tds From Water at Home?

The best way to remove TDS from water at home is by reverse osmosis. You can do this by considering the use of an RO water purifier because it forces the water through a thin membrane that has microscopic spores.

These microscopic spores help in eliminating particles from your drinking water. In many cases, all that can pass are atoms that are smaller than 0.0001 microns.

Total dissolvable solids (TDS) are a rating or value that tells you about the purity of your drinking water. You are supposed to go for a TDS value of 40ppm or lower for the safest results. In many cases, a TDS reading of more than 40 ppm is a clear indication that the water is not safe for drinking.

You can consider checking the TDS meters mentioned above because they possess some of the best features. You can also follow the buyer’s guide to ensure you buy a TDS meter of high quality.

We hope this post has helped you understand the best TDS meters for drinking water and also narrowed your search for the best TDS meters in the market. So, what’s your favorite TDS meter? Feel free and share with us in the comments section below.
