A measuring device and method for a transparent solution

Abstract

The application discloses a kind of measuring device and method for transparent solution, including light source system;Light source system is arranged in the side of transparent water tank, and the solution to be measured is contained in transparent water tank;Double-sided mirror is horizontally arranged on the bottom plate of transparent water tank, and single-sided mirror is arranged in transparent water tank, and is arranged obliquely above double-sided mirror;Wherein, single-sided mirror is provided with light transmission port;Laser beam is incident to the solution to be measured and penetrates light transmission port and is reflected after single-sided mirror, respectively, and first light point B and second light point D are formed on double-sided mirror;Light point sensing system is used to collect and send the position data of first light point B and the position data of second light point D to computing module;Computing module is used to calculate the refractive index and concentration of the solution to be measured according to the position data of first light point B and the position data of second light point D;The device of the application is simple in structure, low in cost, without complicated calibration, simple in calculation process, and the measurement result is high in accuracy.
