Pakadali pano, zida zambiri zoyezera nitrogen oxide pamsika zimazindikira kuchuluka kwa nitrogen dioxide (NO₂) kapena ma nitrogen oxides (NOₓ) posintha koyamba NO₂ mu NOₓ (NO + NO₂) kukhala NO. Komabe, chifukwa cha kusinthika kwa NO₂/NO (zomwe zimadalira ndende yeniyeni ya NO₂), mikhalidwe ina ya m'munda si yoyenera kugwiritsa ntchito nitrogen oxide converter kuti NO₂-to-NO kutembenuka. Pofuna kuthana ndi vutoli, Shandong SINZEN Instrument Co., Ltd. yapanga makina osanthula gasi a SUV-100, omwe amagwiritsa ntchito njira yachindunji ya NO₂ yoyezera poyezera kuipitsidwa. Chowunikiracho chimachokera ku ultraviolet mayamwidwe spectroscopy ndi chemometric algorithms. Imatha kuyeza kuchuluka kwa mpweya monga SO₂, NO, NO₂, ndi O₂. Pokhala ndi miyeso yolondola kwambiri, yodalirika kwambiri, nthawi yoyankha mwachangu, komanso kugwiritsa ntchito kulikonse, itha kugwiritsidwa ntchito kwambiri pakuwunika kwachilengedwe pa intaneti, kuyang'anira mafakitale, kuyang'anira chitetezo, ndi ntchito zina.

Ma nitrogen oxide analyzers ndi zida zofunika zowonetsetsa kuti malamulo akutsatira, kuyang'anira mpweya, ndi kukhathamiritsa njira zama mafakitale. Kuphatikiza apo, amathandizira mafakitale osiyanasiyana kuyang'anira ndi kuwongolera mpweya wa nitrogen oxide, potero amathandizira kuonetsetsa kuti akutsatira malamulo a chilengedwe komanso kuchepetsa kukhudzidwa kwa chilengedwe ndi ntchito zawo. Popereka miyeso yolondola, yeniyeni yeniyeni ya kuchuluka kwa nitrogen oxide (NOₓ), osanthula NOₓ amathandizira kukhazikitsa njira zoyendetsera kuwononga chilengedwe. Izi zikuphatikiza kusintha njira zoyaka moto, kukhathamiritsa kuchuluka kwamafuta a mpweya, kapena kukhazikitsa makina osankha othandizira kuchepetsa (SCR). Mwachidule, akatswiri opanga ma process amagwiritsa ntchito ma nitrogen oxide analyzers kuyeza ndi kusanthula kuchuluka kwa ma nitrogen oxide mu zitsanzo za gasi. Owunikirawa amatenga gawo lofunikira pakuwunika zachilengedwe, kuwongolera mpweya, komanso kukonza njira m'mafakitale osiyanasiyana.

Zotengera mawonekedwewa, zida zimagwiritsa ntchitoDOAagorigoriviti kuwerengetsa kukhazikika kwagasi woyezedwa.

SUV-100 flue gas analyzer imagwiritsa ntchito ukadaulo wa ultraviolet differential optical absorption spectroscopy (DOAS). Imatha kuyeza kuchuluka kwa mipweya yambiri kuphatikiza SO₂, NO, NO₂ ndi O₂, yokhala ndi kuyeza kolondola kwambiri, kudalirika kwambiri komanso kuthamanga kwachangu. Itha kugwiritsidwa ntchito kwambiri pakuwongolera ndi kuwongolera chitetezo pakupanga mafakitale m'magawo monga kuwunika kwa gasi wamafakitale, zitsulo zopangira magetsi, kupanga simenti, kupanga feteleza wamankhwala, makampani opanga mankhwala, kuteteza chilengedwe ndi kafukufuku wasayansi.
