| titleOfInvention | Method and device for measuring the level of Nitrogen Oxide's in the environmental air or exhausted gas by colorimetry |
| abstract | The present invention relates to a method for measuring nitrogen oxide (NO X ) contained in the atmosphere or exhaust gas, and an apparatus for performing the method, and reacts with nitrogen oxide (NO 2 ) to measure the amount of nitrogen oxide. A filter paper sensor 111 coated with a reagent to be developed, a sensor holder 110 for supporting the filter paper sensor at the center, a photodiode 121 for irradiating light of a predetermined wavelength to the filter paper sensor 111, and The photodiode 122 for measuring the remaining light absorbed by the filter paper sensor 111 has a space in which gas can be diffused therein, and the gas is supplied from the supply pipe 123 and the internal space for supplying gas to the internal space. From the photodiode 122 of the measuring unit 100 and the electrical measuring unit 100 consisting of a main body 120 consisting of a discharge pipe 124 for removal, a housing 130 formed with a lid for embedding the main body Specified nitrogen oxides (NO X), the display 200 and the nitrogen oxides consisting of a display 220 for displaying the amplified signal by the amplifier 210 and the amplifier 210 for amplifying the signal related to the amount of (NO X is a colorimetric method characterized by comprising a discharge unit 300 composed of a flow meter 310 and a pump 320 for introducing a gas containing the X into the measuring unit 100 and discharged from the measuring unit 100 Provided is an apparatus for measuring nitrogen oxides (NO x ) in an atmosphere or exhaust gas used. |
