Abstract In view of the shortcomings of the existing device for measuring liquid concentration with complexstructure,high cost, inconvenient use, and inconvenient for schools and some small research institutions,adevice for measuring transparent liquid concentration is designed by grating diffraction method.The devicemeasures the refractive index of liquid according to the relationship between the refractive index and the gratingliffraction angle before and after the liquid to be measured ,and the relationship between the refractive index otthe liquid and the concentration of the liquid is explored through experiments.After the refractive index of theunknown transparent liquid is measured ,its concentration can be obtained by conversion.
