A TDS (Total Dissolved Solids) meter is an instrument used to measure the concentration of dissolved solids in water. It quantifies the total amount of organic and inorganic substances, such as salts, minerals, and metals, present in a liquid.
TDS meters typically provide readings in parts per million (ppm) or milligrams per liter (mg/L). They work by measuring the electrical conductivity of the water, as the presence of dissolved solids increases conductivity. TDS meters are commonly used in water quality testing for aquariums, hydroponics, drinking water assessment, and wastewater management, helping ensure that water meets safety and quality standards.
