Online 4-20mA RS485 Conductivity Controller for Pure Water

Because water contains various dissolved salts, and exists in the form of ions. When a pair of electrodes are inserted into the water, after electrification, under the action of the electric field, the charged ions will move in a certain direction. The anions in the water move to the anode, making the aqueous solution conduct electricity, and the degree of the conductivity of the water is called the conductivity. Conductivity is the reciprocal of resistivity, which reflects the amount of salt in water and is an important indicator of water quality. It reflects the level of electrolytes present in the water. Depending on the concentration of the electrolyte in the aqueous solution, the degree of conductivity of the solution is also different. The solubility of an electrolyte in a solution is analyzed by measuring the conductivity of the solution. This is the basic analysis method of the conductivity meter. In the International System of Units, the unit of conductivity is called Siemen…
