主要功能

• 可测荧光诱导曲线(IC)并进行淬灭分析

  可测光响应曲线(LC)和快速光曲线（RLC）

• 基于不同藻类在450nm，520nm，630nm，660nm的荧光激发光谱差异来计算和分析自然水体藻类成分（蓝藻，绿藻，硅/甲藻），

• 测量蓝藻，绿藻，硅/甲藻的叶绿素a浓度和计算总叶绿素a(Total Chla)浓度。

• 可测量水样的下列光合指标活性：

• 光合效率和光合速率（相对电子传递速率）

• 藻类的潜在ZD光合效率（“生长潜能”）

• 有害藻华(HABs)研究的理想工具

• 藻类的光保护能力

• 藻类耐受强光的能力

• 顶层菜单方便快速启动常规测量，直观显示曲线动态进程

测量参数

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

蓝藻，绿藻，硅甲藻叶绿素a浓度和总叶绿素a浓度等

应用领域

测量野外自然水样或实验室培养的微藻样品的光合作用，标准版是一台超便携的设备，在标准版的基础上加配流通版样品室和蠕动泵套件即可实现连续监测。

WATER-PAM-II还搭载与了PHYTO-PAM-II类似的荧光激发光谱，基于不同藻类在450nm，520nm，630nm，660nm的荧光激发光谱差异来计算和分析自然水体藻类成分（蓝藻，绿藻，硅甲藻），分别测量每个藻中类的叶绿素a浓度和计算总叶绿素a(Total Chla)浓度。

可应用于水生生物学、水域生态学、海洋学、湖沼学等领域，检测限达0.1 μgChl/L。可用于有害藻华(HABs)的早期预警。
