Conductivity is the ability of ions to flow in an electrolyte solution, and is usually expressed by the conductivity per unit length (that is, the conductivity divided by the length of the electrolyte solution). The higher the conductivity, the stronger the flow ability of ions in the electrolyte solution. Measuring the conductivity of water can be used to determine whether there are ions in the water and the concentration of ions. Sources of ions in water include dissolved substances in nature, additives in water treatment, and pollutants. Measuring the conductivity of water can help us understand the quality and contamination of the water.
A conductivity probe with a K constant of 0.01 is usually used in the measurement of low-concentration electrolyte solutions. Due to the low conductivity of the low-concentration electrolyte solution, it may not be possible to measure accurately using a conventional conductivity electrode, but a conductiv…
