PAM-2500——PAM-2100的升级版

野外光合作用研究的首选仪器
Schreiber教授因发明PAM系列调制叶绿素荧光仪而获得首届国际光合作用协会（ISPR）创新奖
1983年，WALZ公司首席科学家、德国乌兹堡大学的Ulrich Schreiber教授设计制造了全世界第一台调制荧光仪——PAM-101/102/103，使在自然光下测量叶绿素荧光成为现实，解决了科学界近50年的技术瓶颈。PAM-101/102/103迅速在植物生理、生态、农学、林学、水生生物学等领域得到广泛应用，出版了大量高水平研究文献。但该仪器比较笨重，不易带到野外。
1992年，WALZ公司首席科学家、调制荧光仪发明人、德国乌兹堡大学的Ulrich Schreiber教授设计制造了全世界第一台便携式调制荧光仪——PAM-2000，并且在植物生理生态学等科研领域得到广泛应用，此后十几年中成为全球最畅销的调制荧光仪。
2003年，WALZ公司在保留PAM-2000所有功能和优点的基础上，结合最新技术，将PAM-2000升级到了PAM-2100。
2008年，WALZ公司在保留PAM-2100所有功能和优点的基础上，结合最新的超便携个人电脑（UMPC）技术，将PAM-2100升级到了完全基于UMPC电脑Windows系统的PAM-2500。
系统描述
PAM-2500采用了独特的调制技术和饱和脉冲技术，从而可以通过选择性的原位测量叶绿素荧光来检测植物光合作用的变化。PAM-2500的调制测量光足够低，可以只激发色素的本底荧光而不引起任何的光合作用，从而可以真实的记录基础荧光Fo。PAM-2500具有很强的灵敏度和选择性，使其即使在很强的、未经滤光片处理的环境下（如全日照甚至是10000 μmol m-2 s-1的饱和光强下）也可测定荧光产量而不受到干扰。因此，PAM-2500不但适合在实验室人工控制的环境下测量，还可以在自然环境中甚至是强烈的全光照条件下开展野外科学研究。
PAM-2500不仅可以连接电脑通过Windows XP SP2系统或Vista系统操作，还可连接UMPC通过Windows XP Tablet PC Edition来操作。UMPC带60G硬盘，1G内存，功能堪比笔记本电脑。
PAM-2500除了标准的叶绿素荧光测量所需配置外，还额外增加了单周转饱和闪光（ST）和多周转饱和闪光（MT），为将来升级P700测量功能埋下了伏笔。
