　　光離子化檢測儀簡(jiǎn)稱(chēng)PID，<a href="http://xiwind.cn/Products-34915871.html" target="_blank">PID光離子化檢測儀</a>可以進(jìn)行有機化合物的檢測，成為儀器更堅固、更可靠檢測有機化合物的普遍工具。由于這些發(fā)展，PID將成為緊急事故監測的專(zhuān)用設備。<br /><br /><div>　　那么PID是什么呢？一起增長(cháng)知識</div><div>　　光電探測器可以測量0.1到2000ppm的VOC和其他有毒氣體。PID是高靈敏度的寬范圍檢測器，可以被視為“低濃度LEL檢測器”。把有毒氣體和蒸汽當成大江，游到大江，LEL檢測儀還沒(méi)有反應，p心會(huì )在你剛淋濕的時(shí)候通知你。<br /> </div><div>　　PID是如何工作的？</div><div>　　PD是使用紫外線(xiàn)燈(UV)光源，用檢測器可以檢測有機物的正負離子)。檢測器測定離子化后的氣體的電荷并變換為電流信號，電流被放大后顯示“PPM'濃度值”。被檢測后，離子再次變成原來(lái)的氣體和蒸汽。PID是無(wú)損檢測器，不燃燒”或通過(guò)長(cháng)期改變待測氣體，可以收集經(jīng)過(guò)PD檢測的氣體進(jìn)行進(jìn)一步測量。</div><div>　　PID光離子化檢測儀是一種可用于緊急事故的靈敏的、可測量各種化學(xué)品的排放手段。正如放大鏡的發(fā)現使指紋更清晰地被識別一樣，PID使救援人員能夠立即檢測出危險物質(zhì)的存在，并進(jìn)行定量測量。放大鏡不能自己認定指紋，但出來(lái)的檢查員可以使用放大鏡頭更快更準確地判斷。對于有害氣體也是如此，雖然用PID無(wú)法判斷有害氣體和蒸汽，但有經(jīng)驗的救援人員可以利用PID更迅速地判斷，進(jìn)行正確的測量。</div><div>　　由于人們越來(lái)越關(guān)注低濃度化學(xué)品的泄漏問(wèn)題，對PID的準確現場(chǎng)測量為救援人員提供了*的幫助。PID可以幫助他們在處理很多緊急事故時(shí)進(jìn)行確認和檢查。</div><p
