4、 Detection principle:

Experimental paper photoelectric photometry method: When gas is blown onto the detection TAB, the paper immersed in a coloring agent combined with TAB will undergo a chemical reaction and change color. For example, after formaldehyde is attached to paper, the reagent contained in the paper will react with formaldehyde to form a compound, and the color will change from white to yellow. The degree of color change can reflect the amount of reflected light received. The rate of change in the intensity of reflected light can be used as a gas concentration response. By setting the detection line in advance, the concentration of the gas can be determined by the response value of the gas being detected.
