Optional copper sleeve for additional protection (especially for sea water) or disposable plastic sleeve facilitates easy cleanup

Technical Description

Design features of the OBS500 include the combination of a backscatter sensor (better at measuring high turbidity) with a second sidescatter sensor (better at measuring lower turbidity). It has a shutter that is opened only during measurements, which reduces the time that algae or other organisms can cling to its optics.

To prevent biofouling and ensure better measurements, the 0BS500 incorporates the ClearSensor” Method (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.

Campbell Scientific offers a disposable, plastic sleeve that can make cleanup a snap, as well as a copper sleeve that can provide additional protection, especially in sea water.

For most applications we recommend the newer OBS501 Sensor
