Low Oxygen Alarm

Question

I wanted to install a vent free propane heater in my ice fishing trailer, the one I am looking at has a low oxygen shutoff, but I would like a little more redundancy. I have an LP/CO alarm that works off of 12 volt, but I was wondering if anyone made an RV grade low oxygen alarm similar to these or similar to a smoke alarm? Most of what I can find online if for industrial use where nitrogen is present of for personal use.

I did the same search.  Here's what I came up with.  CO alarm is easy, and loud.  With an O2 depletion you will wake up gasping for breath.  So, there will be some forewarning.

Both my Olycat heaters have Oxygen sensor shutoff. I have never had one shut down, even w/ no open venting. These oxy sensor heaters were discontinued because they supposedly will not burn at over 6,000 ft elevation. I have never verified that to be true, because I never camp in hi elevation.
