TDS Meter is extremely useful for fast and accurate determination of Total Dissolved Solids in liquid. A high content of dissolved solids elevates the density of water, influences osmoregulation of fresh water organisms and reduces the solubility of gases thereby reducing the utility of water for drinking, irrigation, and industrial purpose. The use of latest microprocessor technology makes the instrument versatile and reliable. The instrument is ideal for testing water, drinking water, waste water brine solution, sea water and soluble salts etc.
