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

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

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ClearSensor^TM 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。
