justify;"><div>　　有毒有害氣體檢測儀也以相對比較的方式測量，其他分析儀器也是如此：儀器首先用零氣體和標準濃度的氣體校準，標準曲線(xiàn)存儲在儀器中。在測量期間，儀器將由待測氣體濃度產(chǎn)生的電信號與標準濃度的電信號進(jìn)行比較，并計算準確的氣體濃度值。因此，儀器的任何時(shí)間零校準和儀器的定期校準是確保儀器準確測量的基本任務(wù)。無(wú)論何時(shí)更換探頭，除了某個(gè)傳感器激活時(shí)間外，還必須重新校準儀器。此外，建議儀器在使用之前對儀器做出響應，以確保儀器的實(shí)際保護。</div><div>　　2、注意各種傳感器之間的檢測干擾</div><div>　　通常，每個(gè)傳感器對應于特定的測試氣體，但任何有毒氣體檢測儀都不是絕對特殊的。因此，在選擇氣體傳感器時(shí)，應盡可能接近其他氣體對傳感器的檢測干擾，以確保其準確檢測特定氣體。</div><div>　　3、注意測試儀器的濃度測量范圍</div><div>　　所有類(lèi)型的有毒有害氣體檢測儀都有自己固定的探測范圍。只有在測量范圍內完成測量才能得到保證。儀器準確測量。如果長(cháng)時(shí)間超過(guò)測量值，可能會(huì )對傳感器造成損壞。</div><div>　　4、注意各類(lèi)檢測儀的使用壽命</div><div>　　所有類(lèi)型的氣體檢測儀都有一定的壽命，即壽命。一般來(lái)說(shuō)，在便攜式儀器中，LEL傳感器壽命長(cháng)，可使用三年左右;光電離檢測器的壽命為四年或更長(cháng);電化學(xué)特定的氣體傳感器具有相對短的壽命。在一到兩年內;氧氣傳感器的壽命最短，大約一年左右。電化學(xué)傳感器的壽命取決于電解液的干燥程度，因此如果長(cháng)時(shí)間不使用，它可以延伸到較低溫度環(huán)境以延長(cháng)使用壽命。由于固定儀器的尺寸相對較大，傳感器的壽命也較長(cháng)。因此，傳感器應盡可能在傳感器的使用壽命期間隨時(shí)進(jìn)行測試，如果失敗，請及時(shí)更換。</div></p>
