of the critical item on a rebreather is the PO2 monitoring. If you
plan on using a rebreather beyond 21 fsw they're pretty much a must
have, even on an SCR in my opinion.
Over the years I have developed a number of PO2 monitoring displays for
different applications. Above is one similar to what I'm currently using on my
rebreather as my primary method of verifying the loop PO2, see the
current one I'm using here.
If you're interested to see the displays I've developed please follow the link below.
Information on displays
You can also see the development
process in the Photo
Gallery under the PPO2 Display section.
