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. They are known for ascertaining fast and accurate measurement of total dissolved solids in given liquids. This instrument is ideal for testing liquids like natural water drinking water treated water waste water brine solution sea water and soluble salt content in liquids

HI3512 is a dual-input professional pH/ORP/ISE/EC/Resistivity/TDS/NaCl/Temperature bench meter with a graphic LCD designed to provide high accuracy and ease of use both in the laboratory as well as in harsh industrial conditions. This instruments is a dual-input model measuring pH, ORP, or ISE and temperature on channel 1 and EC, Resistivity, TDS, and Salinity (utilizing an EC probe) on channel 2.
