Ideal for commercial use, the TDS-3 water quality tester pen includes a carrying case with belt clip. It is highly efficient and accurate due to its advanced microprocessor technology. It features a measurement range of 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1 ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking image.

Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water. TDS, which is based on conductivity, is expressed in parts per million (ppm) or milligrams per liter (mg/L). TDS includes any conductive inorganic element present other than the pure water molecules (H2O) and suspended solids.

TDS affects everything that consumes, lives in or uses water, from fish and plants to plumbing and laboratories.

For people, the lower the TDS level in the water you drink, the more efficiently your bodyâ€s cells are hydrated. The higher the TDS level in water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water.

Use the TDS-3 Tester Pen to:

  • Check the performance of your water filter.
  • Be sure your drinking water is at the right TDS level.
  • Measure TDS levels for other applications.
