A TDS Meter depicts the total dissolved solids (TDS) in a liquid. WaterEx's TDS Meter indicates accurate and fast results. The basis of the process is that the TDS Meter calculates on the basis of the conductivity of the solution, due to the ion formation of salts and minerals in the solution. Thus WaterEx's TDS meter becomes the best solution for testing the potable water, treated water, effluent water, brine solution, sea water etc.
