設(shè)備介紹：
MultiNet?是一款浮游生物自動(dòng)采樣器，它可以在連續(xù)的水層中進(jìn)行水平采樣和垂直采樣。每個(gè)MultiNet?安裝5只（9只）網(wǎng)袋。開(kāi)口面積：Mini型，0.125m2；Midi型，0.25m2，Maxi型，0.5m2；Mammoth型，1m2。整個(gè)系統(tǒng)由甲板控制單元、水下控制單元、不銹鋼框架、網(wǎng)衣、網(wǎng)底管等組成，5（9）只網(wǎng)袋通過(guò)拉鏈連接器連接在不銹鋼框架的帆布部分上。

每次可采5（9）個(gè) 水層樣品 | 準(zhǔn)備入水 | 高強(qiáng)度彈簧提供網(wǎng)口開(kāi)閉的動(dòng)力 | 鈦合金倉(cāng)內(nèi)的高精度步進(jìn)馬達(dá)和控制單元 |
網(wǎng)袋的開(kāi)啟與關(guān)閉是通過(guò)一個(gè)電池驅(qū)動(dòng)的馬達(dá)單元激發(fā)的?？刂凭W(wǎng)袋開(kāi)關(guān)的指令是通過(guò)甲板控制單元和水下單元之間的單芯和多芯電纜傳輸?shù)?。我們可以提供各種網(wǎng)袋，適用于各種標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的應(yīng)用場(chǎng)合。對(duì)于常規(guī)的水平采樣操作，我們推薦您使用孔徑為300um（孔徑從100um至500um都是可選的）的網(wǎng)袋；對(duì)于垂直采樣來(lái)說(shuō)，網(wǎng)孔大小從55um到500um都是適用的。
水下單元中集成一個(gè)壓力傳感器，深度和所有其他系統(tǒng)相關(guān)數(shù)據(jù)會(huì)一起在甲板控制單元的液晶顯示屏上顯示。
水下單元上可以安裝兩個(gè)帶有角度補(bǔ)償功能的電子網(wǎng)口流量計(jì)：一個(gè)裝在水下單元的開(kāi)口內(nèi)，用于測(cè)定通過(guò)網(wǎng)口的水量；另一個(gè)裝在水下單元開(kāi)口外，用于測(cè)定“堵塞效應(yīng)”。
在水平采樣操作中，MultiNet?安裝了一個(gè)V-Fin深度抑制器；在垂直采樣操作時(shí)，一個(gè)不銹鋼支撐安裝在網(wǎng)底管固定器上，以便垂直采樣時(shí)，采樣網(wǎng)能夠安全迅速地降到所需的深度。
操作：
在初始位置的時(shí)候，MultiNet?上的所有網(wǎng)袋是關(guān)閉的。水流可以很自由地流過(guò)框架，并允許采樣器以最適合的速度降到最期望的深度，然后按下甲板單元上的按鈕，可以使第一個(gè)網(wǎng)袋打開(kāi)，當(dāng)操作結(jié)束時(shí)，可以通過(guò)第二個(gè)指令將其關(guān)閉。在第一個(gè)網(wǎng)袋關(guān)閉的同時(shí)，第二個(gè)網(wǎng)袋會(huì)接著打開(kāi)，當(dāng)甲板單元顯示激活的網(wǎng)袋號(hào)碼時(shí)，這些網(wǎng)袋會(huì)重復(fù)以上過(guò)程。在操作Mini型和Midi型MultiNet?時(shí)，第5個(gè)網(wǎng)袋保持敞開(kāi)狀態(tài)，它會(huì)收集從最淺期望深度到表層的浮游生物。在操作Maxi型和Mammoth型MultiNet?時(shí)，第9個(gè)網(wǎng)袋可以在到達(dá)水面之前閉合。
MultiNet入水姿態(tài) MultiNet整裝待發(fā)
CT組件：
MultiNet?與CT組件結(jié)合在一起，擁有一臺(tái)CTD（溫鹽深儀）的完整功能。CT組件由一個(gè)電導(dǎo)率傳感器，一個(gè)溫度傳感器和一塊附加電路板組成，它們集成在MultiNet?的馬達(dá)驅(qū)動(dòng)單元中。根據(jù)UNESCO公式，系統(tǒng)可以從獲得的CTD數(shù)據(jù)，計(jì)算出鹽度、密度和聲速等指標(biāo)。
額外選擇：
√各種參數(shù)的傳感器，如鹽度、溫度、葉綠素a、濁度、姿態(tài)傳感器等
√電池供電的手持終端，當(dāng)在線操作沒(méi)有交流電供電時(shí)，用來(lái)代替甲板控制單元
√適用于6000m和11000m采樣的特殊型號(hào)
