Digital TDS Meter for Water Quality Testing - Accurate TDS, EC & Temperature Tester for Drinking Water, Aquariums, Hydroponics & RO Systems (0-9990 ppm) | Home, Lab & Outdoor Water Testing Tool

A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-EZ can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million).

The lower the TDS level, the purer the water, with 0 being pure H2O. The TDS-3 is great for checking tap water quality, or knowing when to change a filter. The meter does not test for biological contaminants. The TDS-3 is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, and more.
