Online conductivity meter

Product Introduction:

Online conductivity meters use numbers to represent the ability of a solution to conduct current. The conductivity of water has a certain relationship with the amount of inorganic acids, alkalis, and salts it contains. When their concentrations are low, the conductivity increases with the increase in concentration. Therefore, this indicator is often used to infer the total concentration of ions or salt content in water. The measurement principle of the conductivity meter is to place two parallel plates in the solution to be measured, add a certain potential (usually a sine wave voltage) at both ends of the plates, and then measure the conductivity flowing between the plates, which is determined by the voltage and current. Conductivity is actually the resistance of the solution between parallel electrodes measured according to Ohm's law.
