Product Description

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-3TM 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 ppm being pure H2O.
The TDS-3TM is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.)
The TDS-3TM is a great tool for drinking water,water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more.
The TDS-3TM is a rugged model that includes a protective carrying case. This is the world's most popular handheld TDS meter for industry professionals.
