OBS501Smart Turbidity Meter with Antifouling Features

OBS501的设计功能包括将背向散射传感器（更好地测量浊度）与第二个侧分子传感器（更好地测量较低的浊度）组合。它具有仅在测量过程中打开的快门，这减少了藻类或其他生物可以粘在其光学元件上的时间。

OBS501的构建是为了防止沙粒或包装沉积物在快门和传感器主体之间楔入，从而抑制了快门的运动。为此，设计了OBS501的快门和身体，以消除可能在可能的运动部件之间的平行表面。该探针还采用了冲洗动作，将沉积物向下移出快门后面的空腔。

To prevent biofouling and ensure better measurements, the OBS501 incorporates the ClearSensor Method (U.S. Patent No. 8,429,952. This method uses a shutter/wiper mechanism to protect and clean the optics. With the ClearSensor method, a chamber is also filled with a biocide that continuously leaches out over the optics while the probe shutter is in the closed position.Clearsensor^®and OBS^®注册商标的凸轮吗pbell Scientific.

The OBS501 can sense if the shutter’s motor is working harder than normal. If it is, the shutter moves slightly back and forth to dislodge sand grains before fully opening or closing.

Campbell Scientific提供了一次性的塑料套筒，可以使清理捕捉，以及可以提供额外保护的铜套，尤其是在海水中。
