This instrument quantitatively analyzes a substance by measuring its absorbance at a specific wavelength or within a certain wavelength range. When a certain light source emits a beam of monochromatic light into the measured liquid, part of the light signal transmitted through the measured liquid is absorbed, and the other part is converted into an electrical signal through the solution. After conversion and processing, the amount absorbed by the substance is proportional to its concentration, thus determining the concentration of the measured substance.
This instrument can be used to detect pesticide residues, multiple parameters of food, and other items.
