**主要的就是化石燃料燃燒導(dǎo)致空氣中co2的含量增加，這不但會加劇溫室效應(yīng)，更重要的是會危害人類的健康。由于co2是無色無味氣體，很容易被忽視，當(dāng)co2 被吸入人體內(nèi)，進(jìn)入血液中后，血液里的碳酸濃度增加，血液酸性增強(qiáng)，會產(chǎn)生酸中毒。根據(jù)資料[1]顯示，當(dāng)空氣中C〇2的濃度達(dá)到1%時，人就會感覺到胸悶；達(dá)到3 %時，人的呼吸程度加深，并伴有心悸等癥狀；達(dá)到4%時，產(chǎn)生頭昏、、耳鳴、暈眩等癥狀；達(dá)到6%?8%時，會使人呼吸困難、心跳加快、全身無力，嚴(yán)重的甚至?xí)a(chǎn)生神志不清、肌肉抽搐、痙攣等癥狀；達(dá)到30%時，人就會死亡。因此，有必要對實驗室等一些空氣不流通的室內(nèi)的co2氣體濃度進(jìn)行測量，當(dāng)超過危險濃度值時就需要開窗通風(fēng)。北京口碑好便攜式紅外CO分析儀誠信企業(yè)推薦</p><div

TPS2534［6］。兩探測通道表面分別安裝有濾光片 G20 和 G1。 G20 為參考通道濾光片，透射頻帶中心 4. 0 μm，G1 為氣體測量通道濾光片，透射頻帶中心 4. 64 μm．圖 5 所示為 TPS2534 兩探測窗口濾光片紅外吸收光譜與 CO 吸收光譜的對比圖。可以看出 TPS2534 探測窗口濾光片透射頻帶正好與 CO 吸收峰重合，而參考窗口濾光片透射頻帶遠(yuǎn)離 CO 吸收峰，在此頻帶內(nèi)的光強(qiáng)不被其他氣體吸收，可以完整攜帶光源原始光強(qiáng)信息。熱釋電紅外探測器只響應(yīng)變化的光強(qiáng)，因此需要對光源進(jìn)行一定頻率的調(diào)制。TPS2534 的頻率響應(yīng)曲線。可知 TPS2534 的相對輸出隨著入射紅外光頻率的增加 </p> <p> 而減小，當(dāng)入射紅外光頻率將為 5 Hz 時 TPS2534 的相對輸出降為－ 3 dB．綜合考慮紅外探測器及紅外光源的頻率響應(yīng)特性，將光源的調(diào)制頻率設(shè)定為 2 Hz。 </p> <p> <br /> </p><p> 紅外分析儀測量原理由于各種分子具有不同的能級，除了對稱結(jié)構(gòu)的無極性雙原子分子(如0：、N：、H：)和單原子惰性氣體(Ar、Ne、He)以外的有機(jī)和無機(jī)多原子分子物質(zhì)，在紅外線區(qū)都有特征波長和對應(yīng)的吸收系數(shù)，幾種常見氣體對紅外線的透射光譜如紅外線分析儀是利用(一般用于2—121xm光 </p> <p>

熱傳導(dǎo)式氣體分析儀表是根據(jù)不同氣體具有不同熱傳導(dǎo)能力的原理，通過測定混合氣體導(dǎo)熱系數(shù)來推算其中某些組分的含量。這種分析儀表簡單可靠，適用的氣體種類較多，是一種**基本的分析儀表。但是直接測量氣體的導(dǎo)熱系數(shù)比較困難，所以實際上常把氣體導(dǎo)熱系數(shù)的變化轉(zhuǎn)換為電學(xué) 參量的變化來進(jìn)行測定。熱導(dǎo)式氣體分析儀在氣體檢測領(lǐng)域的應(yīng)用范圍非常***，通常用來檢測氫氣、甲烷、二氧化碳、二氧化硫和低濃度可燃性氣體的含量。半導(dǎo)體式氣體傳感器利用半導(dǎo)體材料表面吸附、脫附氣體分子會引起半導(dǎo) 體電導(dǎo)的變化的原理來檢測氣體濃度的。自應(yīng)用于氣體探測以來，以其靈敏度高、響應(yīng)時間快、經(jīng)濟(jì)可靠等特點而得到迅猛發(fā)展，半導(dǎo)體式氣體檢測儀還具有探測范圍廣、反應(yīng)靈敏、成本低廉的優(yōu)點。但半導(dǎo)體式氣體傳感器的缺點是對氣體的選擇性差，穩(wěn)定性差，使得誤報的概率比其他方法大;此外，如果長時間沒有遇到探測氣體，將會因氧化而對檢測氣體變的不靈敏;還有就是這類儀器的輸出信號是非線性的，
