CCR O2 Cell 3-Pack

Three-cell rebreather heads compare their sensors against each other, and that only works if the cells are comparable. Mixing one new cell into two old ones muddies exactly the signal the electronics vote on.

This pack replaces the set as a set. You can browse the full compatibility table here.

What's in the kit:

• 3x O2 Sensor Type D-05R: galvanic cell with water-repellent head, made and individually tested in Germany; replaces Teledyne R-22D and Maxtec MAX-305.
  

Why this kit:

• One batch, three matched cells: the cleanest baseline a voting head can start from.
  
• Fits Megalodon, rEvo, Poseidon, Sentinel, Prism, Divesoft Liberty, KISS and other three-cell units.
  
• One install date to log instead of three overlapping ones.
  

Good to know:

• NRC's manuals put O2 cell service life at about one year; one pack covers a full annual rotation.

For CCR divers who rotate cells on the calendar, not on failure.
