德國HYDRO-BIOS公司—第三代積分采水器
IWS III- Integrating Water Sampler
積分采水器的設計,是為了與歐盟水框架指令提出的要求相一致，用于對柱狀水體進行積分采樣。
特點：
ü外部電源配備單獨的外殼
ü快速啟動按鈕-啟動采水器，使用之前編程的采樣深度
ü協(xié)議-集成在OceanLab3軟件中
ü自由設定深度范圍
新特點：
ü手持終端或電腦可以用藍牙連接
ü無需連接電纜即可對現(xiàn)場采樣預編程
ü時間-積分采樣（例如可以對水平采樣過程設定起始時間和結束時間）
采水器由內置的壓力傳感器和電子控制單元來控制，頂端還配備了小型的馬達單元，確保對整個柱狀水樣在期望的深度進行完整的采樣。供電由可充電的LiFePo4蓄電池來提供。
IWSIII使用起來非常簡單：
可以對期望深度（開始深度和結束深度可自由設定）進行編程，并將數(shù)據(jù)通過手持終端或電腦的OceanLab3軟件存儲在采水器中。采水器的推薦下降速度會顯示在手持終端的顯示器上，然后采水器在水中下降，電子器件會自動調節(jié)由于船體的不穩(wěn)定或海面的不平靜，使得采水器的下降速度不穩(wěn)定所帶來的采樣誤差。到達結束深度后，采水器中的樣品含量為2.5或5L時被拉起，由于采樣深度可以自由設定，可以獲得不同深度的柱狀水樣。
