设备介绍:                                                                                        

MultiNet®是世界顶级的浮游生物自动采样器,它可以在连续的水层中进行水平采样和垂直采样。每个MultiNet®安装5只(9只)网袋。开口面积:Mini型,0.125m2;Midi型,0.25m2,Maxi型,0.5m2;Mammoth型,1m2。整个系统由甲板控制单元、水下控制单元、不锈钢框架、网衣、网底管等组成,5(9)只网袋通过拉链连接器连接在不锈钢框架的帆布部分上。

网袋的开启与关闭是通过一个电池驱动的马达单元激发的。控制网袋开关的指令时通过甲板控制单元和水下单元之间的单芯和多芯电缆传输的。我们可以提供各种网袋,适用于各种标准的和非标准的应用场合。对于常规的水平采样操作,我们推荐您使用孔径为300微米(孔径从100微米至500微米都是可选的)的网袋;对于垂直采样来说,网孔大小从55微米到500微米都是适用的。

水下单元中集成一个压力传感器,深度和所有其他系统相关数据会一起在甲板控制单元的液晶显示屏上显示。水下单元上可以安装两个带有角度补偿功能的电子网口流量计:一个装在水下单元的开口内,用于测定通过网口的水量;另一个装在水下单元开口外,用于测定“堵塞效应”。

在水平采样操作中,MultiNet®安装了一个V-Fin深度抑制器;在垂直采样操作时,一个不锈钢支撑安装在网底管固定器上,以便垂直采样时,采样网能够安全迅速地降到所需的深度。


操作:                                                                                         

在初始位置的时候,MultiNet®上的所有网袋是关闭的。水流可以很自由地流过框架,并允许采样器以最适合的速度降到最期望的深度,然后按下甲板单元上的按钮,可以使第一个网袋打开,当操作结束时,可以通过第二个指令将其关闭。在第一个网袋关闭的同时,第二个网袋会接着打开,当甲板单元显示激活的网袋号码时,这些网袋会重复以上过程。在操作Mini型和Midi型MultiNet®t时,第5个网袋保持敞开状态,它会收集从最浅期望深度到表层的浮游生物。在操作Maxi型和Mammoth型MultiNet®时,第9个网袋可以在到达水面之前闭合。

CT组件:                                                                 

MultiNet®与CT组件结合在一起,拥有一台CTD(温盐深仪)的完整功能。CT组件由一个电导率传感器,一个温度传感器和一块附加电路板组成,它们集成在MultiNet®的马达驱动单元中。根据UNESCO公式,系统可以从获得的CTD数据,计算出盐度、密度和声速等指标。


额外选择:
√各种参数的传感器,如盐度、温度、叶绿素a、浊度、姿态传感器等

√电池供电的手持终端,当在线操作没有交流电供电时,用来代替甲板控制单元
√适用于6000米和11000米采样的特殊型号
