<div><strong>紅外煙氣分析儀</strong>又名非色散紅外煙氣分析儀，具有測量精度高、響應(yīng)時間快、抗干擾能力強、使用壽命長等特點，一般適用于多種行業(yè)的鍋爐氣體等污染排放在線分析，環(huán)境監(jiān)測，燃燒過程研究等。</div><div> </div><div>紅外煙氣分析儀的主要組件NDIR傳感器是一個紅外源（燈），樣品室或光管，濾光器和一個紅外探測器。樣品室中的氣體的原因根據(jù)特定波長,這些波長的衰減是由探測器測量來確定氣體濃度。探測器有一個在它前面,消除所有光除了選中的氣體分子能吸收的波長。</div><div> </div><div>應(yīng)用領(lǐng)域：</div><div> </div><div>1.

</div><div><strong>紅外煙氣分析儀</strong>使用的注意事項有：</div><div> </div><div>1、開機前，檢查電纜和氣管連接是否正常，有無破損或松落。</div><div>2、開機后，檢查氣路是否暢通，排查冷凝物是否堵住排水管。</div><div>3、開機后檢查儀器的氣密性，確保煙氣不會在氣路中泄漏。(檢查儀器的氣密性，可以堵住進氣口，若儀器的采樣流量示值在2min內(nèi)降至零，表明氣密性合格。)</div><div>4、開機預熱后，用手接觸干燥器上端，感受內(nèi)置冷卻器是否制冷，或者待儀器正常運行后觀察指示燈是否正常閃爍。</div><div>5、開機預熱后，觀察蠕動泵是否轉(zhuǎn)動，是否正常排水。</div><div>6、開機預熱后，觀察儀器主機上的顯示屏讀數(shù)是否正常，儀器內(nèi)部泵及風扇是否轉(zhuǎn)動。</div><div>7、如果儀器配有加熱管，需檢查加熱系統(tǒng)是否正常工作。</div>
