Solution information acquisition device

Abstract

The invention relates to a solution information acquisition device which comprises a base and a circuit part. A vertical plate is fixed on the base. The solution information acquisition device is characterized in that a vessel is disposed on the base, a laser source, a white light source, a first CCD (charge coupled device) image sensor and a second CCD image sensor are disposed on the vertical plate and above the vessel, the laser source is used for generating vertical light beams and oblique light beams, the white light source is used for generating white light beams, an oblique reflector is fixed at the bottom of the vessel, the vertical light beams focused by a convex lens and the oblique light beams reflected by to-be-measured solution irradiate on the first CCD image sensor, and the white light beams penetrate the to-be-measured solution and irradiate on the second CCD image sensor. By light irradiation position measuring through the first CCD image sensor, concentration of known solution can be measured accurately, and pollution caused by solution sampling is avoided. In addition, non-contact measuring has evident advantages in measuring of toxic and corrosive solution.

Description

technical field [0001] The invention relates to a solution information collection device, more specifically, a solution information collection device capable of measuring the height, volume, refractive index, substance concentration and even substance type of a liquid substance. Background technique [0002] In the process of acid-base titration and measurement of solution mass concentration, it is often necessary to detect the pH value and mass concentration of the solution. The method commonly used now is at first solution is sampled, carries out the mensuration of pH value by PH test paper, measures the mass concentration of solution by other methods; But in the obtaining process of solution sample, solution is easily polluted by sampling dropper, for In some occasions where the requirements are very strict, this kind of contact measurement is not allowed. For corrosive and toxic substances, it is also easy to cause pollution. [0003] The laser has a narrow wavelength...
