MultiNet?浮游生物采樣網(wǎng)介紹：
MultiNet?浮游生物采樣網(wǎng)是一款浮游生物自動(dòng)采樣器，浮游生物采樣網(wǎng)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?浮游生物采樣網(wǎng)安裝5只（9只）網(wǎng)袋。MultiNet?浮游生物采樣網(wǎng)開口面積：Mini型，0.125m2；Midi型，0.25m2，Maxi型，0.5m2；Mammoth型，1m2。MultiNet?浮游生物采樣網(wǎng)的整個(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)袋通過拉鏈連接器連接在不銹鋼框架的帆布部分上。

MultiNet?浮游生物采樣網(wǎng)網(wǎng)袋的開啟與關(guān)閉是通過一個(gè)電池驅(qū)動(dòng)的馬達(dá)單元激發(fā)的?？刂凭W(wǎng)袋開關(guān)的指令是通過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300微米（孔徑從100微米至500微米都是可選的）的網(wǎng)袋；對(duì)于垂直采樣來說，網(wǎng)孔大小從55微米到500微米都是適用的。
MultiNet?浮游生物采樣網(wǎng)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)裝在水下單元的開口內(nèi)，用于測(cè)定通過網(wǎng)口的水量；另一個(gè)裝在水下單元開口外，用于測(cè)定“堵塞效應(yīng)”。
在水平采樣操作中，MultiNet?浮游生物采樣網(wǎng)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。

MultiNet?浮游生物連續(xù)采樣網(wǎng)的操作：
在初始位置的時(shí)候，MultiNet?浮游生物連續(xù)采樣網(wǎng)上的所有網(wǎng)袋是關(guān)閉的。水流可以很自由地流過浮游生物連續(xù)采樣網(wǎng)的框架，并允許采樣器以合適的速度降到期望的深度，然后按下甲板單元上的按鈕，可以使第1個(gè)網(wǎng)袋打開，當(dāng)操作結(jié)束時(shí)，可以通過第2個(gè)指令將其關(guān)閉。在第1個(gè)網(wǎng)袋關(guān)閉的同時(shí)，第2個(gè)網(wǎng)袋會(huì)接著打開，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)以上過程。在操作Mini型和Midi型MultiNet?浮游生物連續(xù)采樣網(wǎng)時(shí)，第5個(gè)網(wǎng)袋保持敞開狀態(tài)，MultiNet?浮游生物連續(xù)采樣網(wǎng)會(huì)收集從期望深度到表層的浮游生物。在操作Maxi型和Mammoth型MultiNet?浮游生物連續(xù)采樣網(wǎng)時(shí)，第9個(gè)網(wǎng)袋可以在到達(dá)水面之前閉合。
