The electrode works with a technology in 4 electrodes: an alternating current of constant-voltage is established between a primary''''''''''''''''''''''''''''''''s pair of electrodes in graphite. The secondary''''''''''''''''''''''''''''''''s electrodes in platinum allow of regulate the voltage imposed to primary''''''''''''''''''''''''''''''''s electrodes to reflect of the fouling. The voltage measured between the primary''''''''''''''''''''''''''''''''s electrodes is in function of the resistance of place and so, of the conductivity.

Principle:
TDS (Total dissolved solids, the TDS abbreviation), also known as total dissolved solids, water and all solutes in total, including both inorganic and organic content. Since the organic and inorganic substances like natural molecule was contained in water generally can not be considered, it is generally referred to as the salt content of total dissolved solids.
Salinity is the amount of dissolved salts contained in water per kg, it can be understood as the concentration of salt water.
In general, the higher the conductivity, the higher the salt, the higher the TDS, indicating that more impurities contained in the water. Usually 1TDS = 0.5S / cm.
In a liquid conductor, the current through the freedom of movement of ions generated. According to Ohm''''''''''''''''''''''''''''''''s law: I = U / R = U * G, solution conductivity C: C = G * d / A = G * k (d for the plate distance, A is the plate area, the electrode constant k = d / A [cm-1]).
4 electrode: Through two capacitor plates is equivalent to four electrodes to measure conductivity.
