We use ~100 of them at Weill Cornell. We have used them for >5 years and have had no issues. They still have to be bump tested and calibrated annually, but having a sensor that doesn't go out "frequently" is a huge plus.

Subject: [DCHAS-L] Recommendations for Oxygen monitors?
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.
