Maintenance and repairs

Support kits

To simplify maintenance of your data logger, RBR sells Support kits with
enough O-rings, and silicone grease for 5 deployments. Please contact RBR for
more information or to place an order.

O-rings

The single most important item of maintenance on any RBR submersible data
logger is care of the O-rings. Any kind of water leak can damage the circuitry
beyond repair and cause complete data loss. Every logger's seal depends
upon its O-rings, not the end cap tightness. Proper O-ring maintenance,
therefore, is crucial.
Please see Appendix B (p.45) for O-ring specifications for each logger.
Inspecting O-rings

O-rings must be undamaged and the mating surfaces free from particles of grit,
hair or small scratches in order to preserve a seal. Before deploying the logger,
carefully inspect the O-rings that are required to maintain a seal. 1050/2050
series loggers depend upon one O-ring in the end cap. The plastic XR series of
loggers have one O-ring for each end cap and two for each detachable sensor.
Titanium versions of the XR series loggers have a backup ring in each end cap
as well. TR-1060 loggers have one O-ring seated in the middle part of the logger
case.
Important: O-rings may lose elasticity over time due to pressure,
even when the logger is not deployed. We strongly suggest that
the O-rings be replaced regularly, e.g. before every deployment,
or after change of batteries, or at least once a year.
