水樣調制葉綠素熒光儀——WATER-PAM
主要功能
可測熒光誘導曲線并進行淬滅分析
可測光響應曲線和快速光曲線（RLC）
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）
藻類的潛在光合效率（“生長潛能"）
藻類的光保護能力
藻類耐受強光的能力
51 個內置模式菜單，方便參數設置和標準測量
系統 I 用于浮游植物研究，系統 II 用于大型藻類研究，系統 III 用于連續監測水體光合作用
測量參數
Fo, Fm, Fv/Fm, F, Fm’, Fo’, Y(II) 即 ΔF/Fm’, qP, qN, NPQ, ETR 和 PAR 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，三套系統可供選擇，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。可用于有害藻華的早期預警。與 PHYTO-PAM 的區別在于，WATER-PAM 不能進行浮游植物分類。
