Common Accessories

31569
 
The 31569 is a copper sleeve that protects the OBS501 and is especially useful in sea water. It can reduce biological fouling of the sensor.
31570
 
The 31570 is a disposable plastic sleeve for the OBS501 that facilitates cleanup.
 
The 27225 carrying case can hold two OBS501 probes, making it easier to carry the probes to field installations.
27573
 
The 27573 is a 2 m cable that connects the OBS501 to a PC, allowing the probe to be configured.
27785
 
Campbell Scientific offers a choice of cables for attaching an OBS501 to the datalogger. The cables differ in their length. The 27785 provides a 5-m length.
27786
 
Campbell Scientific offers a choice of cables for attaching an OBS501 to the datalogger. The cables differ in their length. The 27786 provides a 10-m length.
27787
 
Campbell Scientific offers a choice of cables for attaching an OBS501 to the datalogger. The cables differ in their length. The 27787 provides a 20-m length.
27788
 
Campbell Scientific offers a choice of cables for attaching an OBS501 to the datalogger. The cables differ in their length. The 27785 provides a 30-m length.
 
OBS501CBL-L OBS501 or OBS500 Field Cable
 
Warning: This has a long delivery time compared to the others. The OBS501CBL-L attaches an OBS501 turbidity sensor to a datalogger. This cable has a user-specified length; lengths between 31 and 76 meters can be ordered. A user-specified cable length takes more time to manufacture.
Cable Length - show details
-L m per sensor cable

Allowed values: 31-305 m, increments of 1 m

 
When the 20915 is ordered, Campbell Scientific will perform a 5-point sedimentation calibration for the OBS501. The customer must send Campbell Scientific a dry sample of sediment from the water that will be monitored.

Other Accessories

33815
 
The 33815 makes it easier for you to connect wires from multiple SDI-12 sensors into one set of terminals on a data logger. The 33815 uses six DIN-rail mountable (pn 27479) 6-wire terminal blocks. The 33815 jumpers two connectors together at a time (pn 32918). This setup allows up to 11 SDI-12 sensors to be connected to one set of terminals on a data logger.

Replacement Parts

 
The 30893 kit includes a hex driver, flat screwdriver, replacement floating nut for the shutter, and replacement screws.

Services

 
The 27781 provides a recalibration of the OBS501. The 13-point calibration uses six calibration standards for backscatter, six calibration standards for side scatter and a zero point in clear water for both sensors. Before and after calibration sheets are supplied. All factory recalibrations require an RMA (Returned Material Authorization).
