Conductivity Sensor

Wellkonix Conductivity Sensor meter allows us to measure the level of conductivity in solutions. Conductivity is an ability of materials (solutions, metals or gases) to pass an electric current. While all materials possess the ability to pass electric currents, the degree of such ability can vary. Substances with conductive aqueous solutions are referred to as electrolytes. These electrolytes are able to break down into ions when dissolved in water, thus creating free ions in the solution. Acids, bases, and salts are examples of electrolytes. Substances with non-conductive aqueous solutions are referred to as nonelectrolytes. These substances are often composed of covalent bonds, and examples include Carbon-containing compounds, fat, and sugar. Solutions with high concentration of ions will exhibit high conductivity. On the other hand, solutions with low concentration of ions will result in small conductivity reading. A few factors that effect conductivity measurement are temperature, concentration of ions, and the nature of ions present in the solution. Potassium Chloride (KCl) is a strong electrolyte that completely ionizes in water, thus possessing high conductivity. Acetic acid is a weak electrolyte that does not fully ionize in water, conducting low amount of electricity.
