| eCCR controls
Hello,
I newbie stupid question as I reserach rebreathers:
While eCCRs certainly do a good job at preventing to low a PO2 they don't limit the high PO2 -- the most they do is alert you that the PO2 is too high (i.e. on ascent). With all the advances in electronics it seems a trivial amount of work to control the diluent with auto addition to prevent the PO2 for exceeding the 1.4 (1.6) limits.
Certainly following proper protocols will prevent this, but one aspect of having an eCCR is to have something managing the rebreather for you. Why limit that management to the low end when the high end is just as leathal.
