Appendix B – O-ring specifications
Each 1050 or 2050 series logger has one user replaceable O-ring located above
the thread of its end cap. Titanium versions also have a backup ring in the same
groove.
XR series loggers have one user replaceable O-ring located in each end cap
above the thread. Titanium versions also have a backup ring with each O-ring in
the same groove.
TR-1060 loggers have one O-ring seated in the middle part of the logger case.
Important:

before every deployment, or after change of batteries, or at least once a
year.
