设备介绍：                                                                                        

MultiNet?是一款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ξ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ζ　垂直采样操作时，一个不锈钢ζ　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。

设备特点：

√水平操作和垂直操作

√容易操作
√双向通讯
√标准深度3000米，可选工作深度6000米，11000米
√长距离FSK自动测量记录传导
√电量消耗低

√电池供电的水下单元
√EC-认证(CE)EN 50081-1,EN 50082-1
√操作温「度范围-40℃ ~ +85℃

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，并允许采样器以合适的速度降到期望的深度，然后按下甲板单元上的按钮，可以使第1个网袋打开ζ，当操作结◆束时，可以通过第↙2个指令将其关闭。在第1个网袋关闭的同时，第2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?时，第5个网袋保持敞开状态，它会收集从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ㄨ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
