Background

Total Dissolved Solids (TDS), also known as Total dissolved solids, is measured in milligrams per liter (mg/L) and indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Higher TDS values indicate more solutes in the water. Total dissolved solids refers to the total amount of total solutes in the water, including both inorganic and organic content. Generally, the salt content of the solution is known approximately by the conductivity value, and generally, the higher the conductivity, the higher the salt content, and the higher the TDS. Among inorganic substances, there may be inorganic substances in molecular form in addition to components dissolved in ionic form. Since organic matter and inorganic matter in molecular form contained in natural water are not generally considered, the salt content is generally referred to as total dissolved solids.

The conductivity of the solution can be measured by the electrode method. The principle of measuring the conductivity is to put two plates (or cylindrical electrodes) parallel to each other and at a fixed distance L into the solution to be measured, and apply a certain potential (usually sine wave voltage, frequency 1-3 kHz, to avoid electrolysis of the solution) to both ends of the plates. The inter-plate conductance was then measured by a conductivity meter.

The soluble total solids content of water can be approximately reflected by measuring the conductivity of the aqueous solution. This method has been widely used in household appliances such as water purifiers, etc. However, since the conductivity is greatly influenced by the temperature of the solution, temperature correction is often required for detection in order to obtain a relatively accurate detection result, and a common conductivity electrode does not have the capability of sensing temperature and conductivity at the same time, or the temperature detection mode is inconvenient to install and use; in addition, for consumer products with high appearance requirements, such as intelligent water cups, intelligent kettles, table-board type small water purifiers and the like, the aesthetic degree of the sensor is also an important consideration, and the thick electrodes and the protruding probes are obviously not suitable for use.
