原理是電化學(xué),具體可百度之。臭氧的影響這個不用擔(dān)心,我買的是德國MRU的optimal 7,當(dāng)時我給那邊工程師聯(lián)系的時候的問題就包括臭氧的影響。 問題:the simulated flue gas contains hundreds ppm of sulfuric acid , nitric acid and ozone and I notice that in the user manual : Caution: Exposure to acids; aggressive gases such as sulphur.....etc. can damage, reduce the life of, or destroy the sensors.(Page 8). My question is that:Do I need to remove these acids and aggressive gases first and then detect SO2 ,NOx ? or I can directly use optima 7 without any pretreatment. 人家的回復(fù):this standard warning wants to avoid the exposure to aggressive gases in the percentage range. |
