3.2  DO sensor (OxyGuard) care and maintenance

Storage

Store the OxyGuard dissolved oxygen sensor in the dedicated storage cap to minimize fluid loss. Storage caps are 
provided with the instrument. Contact 

RBR

 

if a replacement is needed.

O-ring

The red O-ring of the OxyGuard sensor serves two 
purposes:

To retain the electrolyte during storage
To balance pressure during deployments

There are two positions for O-ring on the OxyGuard 

sensor, "Transport" and "Measurement". 

During transportation or storage, move the red O-ring of 
the Oxyguard sensor to the "Transport" position, closing 
off the port on the side of the cell.

Before deployment, move the O-ring to the 
"Measurement" position to maintain the pressure 

balance.  

After deployment, return the O-ring to the "Transport" 

position. 

Support kit

RBR offers an OxyGuard sensor support kit that includes:

Membrane tool
Electrolyte solution (250ml)
Fast response membranes
Replacement O-rings
Oxyguard Support Kit and Refurbishment Guide

Check the state of your DO sensor before deployment. Look for any damage to the membrane, cloudiness of the 
electrode, and buildup on the anode. If you find any damage, refurbish and re-calibrate the sensor.

Refer to Oxyguard Support Kit and Refurbishment Guide, included with the support kit, for instructions on refurbishing 
your sensor. See 

Ruskin User Guide

 for instructions on calibration.
