Poseidon 02 Sensor
Oxygen sensors are consumables and should be changed when your Poseidon rebreather has a hard time reading the correct 02 levels in your loop or they have been in use for over 1 year.
You may need to change your O2 sensors if the following occurs:
Recurrent C1 alarms when diving
Hyperoxic linearity test failure
Recurrent T53 failure
