There are several methods in use for controlling the O2 level. The difficulty is to a find solution that is relatively simple and that maintains acceptable levels of O2 even when depths and diver workloads change.
What is DiveCAN® and why should I care?
March 22, 2016
Digital communications are clearly replacing analog communications in computer based devices. As more digital communication becomes integrated into rebreathers, Shearwater went in search of the best digital solution.
We looked at basic serial and at higher level serial like HDLC and SDLC as well as microprocessor communication protocols...

Why do you calibrate a CCR with pure Oxygen?
September 15, 2015
We frequently get asked the question as to why we use O2 as a calibration source for oxygen sensors in closed circuit rebreathers (CCR). A CCR diver often has multiple gasses available, any of which could in theory be used for calibrating the O2 sensors in the...
