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.

The O2 monitors are working well and doing a great job! Alarm relays are configured with the exhaust fan and is triggered a couple of times a day if we have LN2 bottles in the area. Excellent product, repeatable, and reliable as advertised.

Purchased the PureAire O2 monitoring system and once it arrived had it installed, very simple and neat. After a 4 minute start up sequence it automatically started to operate. We found that this unit is so flexible we can use it in almost any location, so future purchases will not be an issue. We also tied it into a strobe both in and out of the lab area and it was also tied into our on station Fire Response Team. No calibration for 10 years and 3 year warranty with no cell replacement costs are just a plus for this unit.

We buy a lot of oxygen monitors and PureAire’s are by far the best! They have a much longer warranty than other brands and the product is a lot higher quality. Their customer service is also fantastic. Everyone is super helpful and they got us some monitors very quickly when we were in a tight spot. Highly recommended!

We have been using PureAire O2 Monitors at The Cryo Spa in Fort Worth for over 3 years now and they have always worked perfectly. I would highly recommend PureAire for any oxygen monitoring needs! Thanks for your quality products and professional customer service!

My co-worker started using these devices down at Yale University, PureAire O2 depletion monitors. After years of dealing with expensive long lead MSA Tox Alert monitors it was a breath of fresh air to be introduced to PureAire!! Easier to setup, much longer life on the sensor, 10 year sensor is great news, considering the O2 depletion monitors I’ve used in the past need recalibration or replacement every year. Look forward to installing these devices at Yale New Haven Hospital.

We tested the O2 monitor and it was very nice compared to the one another department in our company has which uses disposable sensors. The calibration free feature really helps us not only reducing the calibration costs, but also the amount of work needed to arrange calibration. Thank you for the good product.
