Product Details
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 stands for Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS meter tells 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. A TDS meter is great for checking your tap water quality and knowing when to change a filter. ISPRING TDS2 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. This is the world's most popular handheld TDS meter for both industry professionals and household use.
