My institution usually uses the PureAire 10-yr maintenance-free units, which are about $1k ea. Be aware they have a lot of interferences, so you may need electrochemical detectors in some lab areas where you have solvents, sulfur compounds, etc. in use.

Hi all,
Does anyone have recommendations for an oxygen sensor? We have a lab that is looking to purchase one for a room that will be storing liquid nitrogen.
Thanks!
