系统组成:



主机:浅水版Cytosub (水下20米),含CytoSense所有基本配置

浮标模块:包括浮标、太阳能电池板、充电电池、浮标灯、电子系统、无线传输装置和采样管防水连接器等。根据用户需要,也可扩展为易拆卸浮标模块,这样用户可以非常方便的在CytoSense(室内用)和CytoBuoy(在线监测)间转换。
注意:野外在线监测时不仅于以浮标作为平台,其他平台也可,只要可以具备放置CytoSense的空间及供电即可。同时,增加Bacterial staining module,可实现水体异养微生物自动染色和在线分析,可在线检测藻类、细菌、浮游动物及沉积物等颗粒。具体信息请。

三、水下浮游植物流式细胞仪——CytoSub 


主机:台式机CytoSense是防溅水设计,可以在野外使用,但不能水下使用。CytoSense加上一个水下模块(SUB MODULE)就组成了水下式流式细胞仪CytoSub。
水下模块:一个耐受200 m水深压力的防水外壳,阀门和进样环路部分(包括循环泵),电子控制单元,数采,水下连接器和支架。
