主要功能

• 可測熒光誘導曲線(IC)并進行淬滅分析

  可測光響應曲線(LC)和快速光曲線（RLC）

• 基于不同藻類在450nm，520nm，630nm，660nm的熒光激發光譜差異來計算和分析自然水體藻類成分（藍藻，綠藻，硅/甲藻），

• 測量藍藻，綠藻，硅/甲藻的葉綠素a濃度和計算總葉綠素a(Total Chla)濃度。

• 可測量水樣的下列光合指標活性：

• 光合效率和光合速率（相對電子傳遞速率）

• 藻類的潛在最大光合效率（“生長潛能"）

•   有害藻華(HABs)研究的理想工具

• 藻類的光保護能力

• 藻類耐受強光的能力

• 頂層菜單方便快速啟動常規測量，直觀顯示曲線動態進程

測量參數

Fo, Fm, Fv/Fm, F, Fm’, Fo’, Y(II)=ΔF/Fm’, qP, qN, NPQ, Y(NPQ), Y(NO), ETR, α，Ik，ETRmax

藍藻，綠藻，硅甲藻葉綠素a濃度和總葉綠素a濃度等

應用領域

測量野外自然水樣或實驗室培養的微藻樣品的光合作用，標準版是一臺超便攜的設備，在標準版的基礎上加配流通版樣品室和蠕動泵套件即可實現連續監測。

WATER-PAM-II還搭載與了PHYTO-PAM-II類似的熒光激發光譜，基于不同藻類在450nm，520nm，630nm，660nm的熒光激發光譜差異來計算和分析自然水體藻類成分（藍藻，綠藻，硅甲藻），分別測量每個藻中類的葉綠素a濃度和計算總葉綠素a(Total Chla)濃度。

可應用于水生生物學、水域生態學、海洋學、湖沼學等領域，檢測限達0.1 μgChl/L。可用于有害藻華(HABs)的早期預警。
