Total dissolved solids (TDS), also known as total dissolved solids, is the total amount of all solutes in water, including both inorganic and organic content. Since organic matter and molecular inorganic matter contained in natural water are generally not considered, the salt content is generally referred to as total dissolved solids.
Salinity refers to the amount of dissolved salts per kilogram of water, and can be understood as the concentration of salt in the water.
In general, the higher the conductivity, the higher the salt content, and the higher the TDS, which means that the water contains more impurities. Generally 1TDS=0.5μS/cm.
In liquid conductors, current is generated by the movement of free ions. According to Ohm's law: I=U/R=U*G, solution conductivity: C=G*d/A=G*k (d is the distance between the plates, A is the area of the plates, and the electrode constant k=d/A[ cm-1]).
Electrode type: The conductivity is measured by using 4 electrodes equivalent to the two plates of the capacitor.
Inductive type: The transmitting coil generates an alternating magnetic field, which generates an induced voltage in the medium to move the positively or negatively charged ions in the liquid, and form an alternating current in the liquid. The current generates an alternating magnetic field in the receiving coil, and the circuit has a certain proportional relationship between the induced current generated by the coil and the conductivity, thereby measuring the conductivity. Since ion clusters are formed on the positive plate of the small face, the free movement of positive and negative ions is hindered, and it is impossible to measure solutions with high ion concentration, so an inductive sensor is required.
