Description 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. Supplied in an attractive plastic case along with standard solutions for easy calibration. Features Microprocessor-based fast reliable and accurate measurements. Replaceable Electrode Module Waterproof Impact resistant ABS Housing Large LCD display for reading convenience Easy Single Point Calibration Available in a portable pack.
