First test of Oxygen Rebreather

The rebreather oxygen system has been tested in a simple form. Jim Murray has put together a re-configurable system using simple plumbing parts. This allows us to test different configurations to work out which is best.

The tests were very encouraging. The CO2 scrubber lasted much longer than predicted and the heat and moisture build-up were much less than predicted.

Now we know what configuration works best, we will continue testing the rebreather in cold and altitude conditions.
