Conductivity meters are used to measure the ability of a substance to conduct electricity. In general, these devices are used in laboratories and industry to measure the level of impurities in a solution. Conductivity meters can also be used to detect leaks in electrical conductors.
Conductivity meters are based on the principle that electricity flows through a conductor when a potential difference is applied to it. The magnitude of the current flowing through the conductor depends on the resistance of the conductor
Conductivity meters can be used to measure the amount of impurities in a solution. The strength of a solution increases as a function of the concentration of impurities in the solution. In this way, conductivity meters can be used to measure the purity of a solution.
