德国HYDRO-BIOS公司—第三代积分采水器
IWS III- Integrating Water Sampler
积分采水器的设计,是为了与欧盟水框架指令提出的要求相一致，用于对柱状水体进行积分采样。
特点：
ü外部电源配备单独的外壳
ü快速启动按钮-启动采水器，使用之前编程的采样深度
ü协议-集成在OceanLab3软件中
ü自由设定深度范围
新特点：
ü手持终端或电脑可以用蓝牙连接
ü无需连接电缆即可对现场采样预编程
ü时间-积分采样（例如可以对水平采样过程设定起始时间和结束时间）
采水器由内置的压力传感器和电子控制单元来控制，顶端还配备了小型的马达单元，确保对整个柱状水样在期望的深度进行完整的采样。供电由可充电的LiFePo4蓄电池来提供。
IWSIII使用起来非常简单：
可以对期望深度（开始深度和结束深度可自由设定）进行编程，并将数据通过手持终端或电脑的OceanLab3软件存储在采水器中。采水器的推荐下降速度会显示在手持终端的显示器上，然后采水器在水中下降，电子器件会自动调节由于船体的不稳定或海面的不平静，使得采水器的下降速度不稳定所带来的采样误差。到达结束深度后，采水器中的样品含量为2.5或5L时被拉起，由于采样深度可以自由设定，可以获得不同深度的柱状水样。
