概览

OBS500 是一款水下使用的浊度探头,带有主动防污损功能,可在生物活性的水体中提供更好的测量,高低浊度都可以测量。它输出SDI-12数字处理的信号,Campbell Scientific大多数的数据采集器都能测量。美国专利号 8429952

优势与特点

  • Dual backscatter and sidescatter sensors used to measure turbidity
  • Patented ClearSensor antifouling method for better measurements in biologically active water
  • Shutter/wiper mechanism keeps lenses clean
  • Refillable biocide chamber prevents fouling
  • Disposable plastic sleeve facilitates cleanup
  • Optional copper sleeve for additional protection (especially for sea water) or disposable plastic sleeve facilitates easy cleanup

技术说明

OBS500 的设计特点包括两种浊度传感器的组合,一个后散射传感器(更适合测量高的浊度),另一个是侧散射传感器(更适合测量低的浊度)。OBS500的快门仅在测量期间打开,这减少了藻类或其它有机物附着在OBS500的光学镜头上的时间。

为了防止生物污损和确保更好的测量,OBS500 使用了专利的ClearSensorTM 防污损方法(专利号:8,429,952)。这种方法使用快门/镜头刷机制来保护和清洁光学镜头。对于ClearSensor 方案,腔室里还注入杀生物剂,连续浸出覆盖镜头表面,当探头的快门处于关闭位置的时候。

坎贝尔提供可遗弃的塑料套,可让清洁更迅速;也提供铜套,可提供更多的保护,特别是海水应用。
