APDA-371

環境粉塵監測儀

顆粒物以多種方式污染我們的大氣。例如,它可以由不同的工業生產過程、廢物燃燒、煤炭開採或汽車廢氣產生。 APDA-371 使用經過業界驗證的 β 射線衰減原理,自動測量並記錄空氣中顆粒濃度水準(以毫克或微克/立方公尺為單位)。每小時,一個小型碳 14 元素會透過一塊乾淨的填充膠帶發出恆定的高能量電子源(稱為 β 射線)。這些 β 射線由靈敏的閃爍偵測器偵測和計數,以確定零讀數。

APDA-371 會自動將膠帶點推進到樣品噴嘴,然後吸塵器將經過測量和控制的含塵空氣量拉過濾帶。每小時,這個髒點會被放回 β 源和探測器之間,從而導致 β 射線訊號衰減,該訊號用於確定濾帶上顆粒物質的質量。 APDA-371 空氣污染粉塵懸浮微粒 (SPM) 分析儀可確保長期穩定性和自我診斷功能以及氟樹脂膠帶的高效收集。測量原理根據 EU 和 EPA 法規運行,並且還獲得了 TueV 的型式批准。
