I was on a site with no internet access this week. This might be too late to do any good.


First, no: No experience with PureAire monitor.


Second, Jefferson Laboratory (formerly Continuous Beam Accelerator Facility), Newport News, VA, has a good research-oriented booklet on oxygen deficient atmospheres due to high nitrogen levels. We know people there but do not work there.

Do any of you have experience with the Oxygen Monitoring system by PureAire? It uses a zirconium oxygen sensor with a10 year life expectancy. I am shopping for a monitor for a room that houses liquid nitrogen and NMR.
