Digital Water Purity Tester (TDS Meter)
A TDS Meter indicates the amount of Total Dissolved Solids (TDS) in a solution. Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution then converts that figure to an estimated TDS reading. TDS can serve as a general indicator of total organic and inorganic contaminants in a water sample. Maintaining proper TDS levels is particularly important for aquariums and fish ponds - TDS levels can change dramatically over time, with dire consequences for the health of resident fish. Gardens may also benefit from water with proper TDS levels. Consult your veterinarian or pet store for recommended TDS levels for aquariums and ponds.
