Subject: Re: O2 analyser

  When I had a one-day introductory course with the Prism rebreather, I was
told that ppO2 sensors are little fuel cells that produce electricity at a
rate proprtionate to the ppo2; what you see showing the ppO2 is a microammeter
reading that current. As they are fuel cells:-
  (1) What fuel do they use?
  (2) How long do they last?
  (3) How to refuel them when they run empty?
  (4) If a rebreather has ppO2 sensors in, so they don't burn themselves up
for no purpose, it should be possible, if the rebreather is going to be in
store for a long time without being used, to:-
    (a) take the sensors out and keep them in an oxygenless atmosphere, or
    (b) fill the rebreather with oxygenless gas.
