The ppm pen is the perfect way for measuring and tracking your waters levels of TDS to make sure your water filter is doing its job. With this water ppm tester, you wont just need to take the filter manufacturers word that it reduces TDS in your water; you can test!

Test before you drink!
We cannot visually determine the purity of drinking water. Even seemingly clear and transparent water may contain a lot of impurities. That's why it's essential to test your water before drinking it. The water tester is just right for detecting the three major impurities in water, including heavy metal ions, Ionic organic matter, and soluble salts of calcium and magnesium. Don't take any chances with your health - invest in a TDS meter today!
What Is TDS in PPM And Why Should We Care?
TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. The lower the TDS level in the water, the more efficiently your bodys cells can use the water. Conversely, higher TDS levels can indicate water that is more difficult for your body to use and has more contaminants.
