TDS-3 Portable Digital TDS Meter for Water Purity Tester

The TDS-3 Portable Digital TDS Meter is a handheld device used to measure the Total Dissolved Solids (TDS) in water. TDS refers to the concentration of dissolved substances such as salts, minerals, metals, and other organic and inorganic compounds in water. This meter is commonly used to test the purity or quality of water, such as from drinking sources, aquariums, pools, or water filtration systems.
