water TDS test pen
TDS: TDS includes a mixture of inorganic salts, mostly sodium, chloride, potassium, calcium, and magnesium. Rather than testing the particular components, TDS is monitored by measuring the conductivity of the water with a digital meter. There is no test strip or color disk kit that can be used here, although at least one conductivity meter interfaces with a smartphone. TDS = Total Dissolved Solids, which is any salt, metal, or mineral in the water. With the push of a button, the TDS 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 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 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 is a rugged model that includes a protective carrying case.
