Using the simplification of the experimental steps as a starting point, the photoelectric ellectlaboratory instrument is used to measure the refraetive index and conductivity of liquids.Combined with therelationship between different physical properties of liquids, the magnitude of photocurrent in differentconcentrations of the same liquid is measured. With the help of Origin software ,the equations of the calibrationcurves of photocurrent and liquid refractive index and conductivity were fitted. The refractive index andconductivity of the liquid can be calculated by substituting the magnitude of the measured photocurrent.
