In industry most folks use three or four sensors but the instruments can be configured with only the oxygen sensor. They are smaller in surface area than most cell phones but are thicker.

Subject: [DCHAS-L] Portable Oxygen Monitor Recommendations
Hello,
I am looking for recommendations for portable oxygen monitors to be used when doing work with cryogenic gases to be worn as a backup to our wall-mounted sensors in a small room. I would like for it to have a pump but it does not need to
detect multiple gases.
Thank you,
Monique
