Product DescriptionThe instrument adopts chemiluminescence method. The basic working principle is as follows: no reacts with O 3 to produce no 2 with energy. When no 2 with energy releases energy, it produces fluorescence of specific wavelength. The intensity of this fluorescence is linear with the concentration of No. the photocell transforms the light signal into electrical signal and measures the concentration of No. The method of sample gas detection is as follows: NO x in the sample gas enters into the instrument and is divided into two channels. One way of sample gas enters into the reaction chamber, and no in the sample gas reacts with O 3 to measure the concentration of No. the other way of sample gas enters the conversion furnace to convert no in the sample gas, and then enters the reaction chamber to react with O 3. The measured value is no 2 + no = NO x. the concentration of no 2 is obtained by subtracting no concentration from NO x concentration.
