An electrical conductivity meter measures the electrical conductivity in a solution. EC meters are commonly used in hydroponics (ppm meter), aquaculture (pool maintenance) and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.
A TDS Meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solids in it. Since dissolved ionized solids such as salts and minerals increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that.
Dissolved organic solids such as sugar and microscopic solid particles such as colloids, do not significantly affect the conductivity of a solution so a TDS meter does not include them in its reading.
