APSA-370

環境二氧化硫監測儀

APSA-370 是一款使用紫外線螢光連續監測大氣 SO2 的裝置。 APSA-370 採用專有的內部乾式採樣裝置來實現最高水準的靈敏度和準確性。乾法由於其維護要求極低，能夠連續監測並即時分析未改變狀態的氣體，因此已成為監測大氣污染的首選方法。

產品分類: Ambient

Base product: AP-370系列

• 抗濕氣幹擾的紫外線螢光偵測器；低量程：0-0.05 ppm F.S.

• 除了FDP 測量之外，偵測器設計具有高SO2 選擇性，且無需補充氣體。

• 具有選擇性薄膜的整體式HC 切割器消除了乾擾成分。

• 內含燈強度補償器。

• 使用內建惰性PTFE 樣品入口過濾器。
