A Few Words from
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!
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 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.
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.
Oxygen deprivation is a silent killer. Oxygen-depleting gases, such as nitrogen, argon, and helium, are odorless and colorless, making leaks impossible to detect, unless appropriate monitoring is in place.
PureAire oxygen deficiency monitors can be used to monitor nitrogen, argon, and helium. Carbon dioxide can also be monitored with PureAire’s dual oxygen/carbon dioxide monitor.
PureAire uses a proprietary, non-depleting, zirconium oxide sensor that will last up to 10 years in a normal environment without needing to be replaced.
PureAire’s sensors do not operate under partial pressure, meaning that a PureAire sensor will not need to be adjusted to account for different elevations. Additionally, the sensors will not drift due to changes in barometric pressure.
In contrast, other gas detection companies use depleting, electrochemical sensors. These sensors, because they are depleting, operate for 1-2 years before needing to be replaced. Electrochemical sensors do not offer long-term solutions to companies committed to safety.
PureAire sensors are built to last 10years. Often, the sensors work much longer. In fact, some of our first customers who started using PureAire products in 1997 report that the sensors are still in operation today.
On the other hand, an oxygen monitor that uses a depleting, electrochemical sensor is like a battery in that, as the sensor depletes, it begins to lose its power and responsiveness. In order to operate accurately, electrochemical sensors must be calibrated frequently.
PureAire sensors do not need to be calibrated. Because they are made of non-depleting zirconium oxide,the sensorswill never need calibration. However, a visual check of the monitor should be done every year to verify that the sensor is functioning properly.
In contrast, electrochemical sensors, because they deplete over time, will need to be calibrated every 2-3 months and totally replaced every 1-2 years.
Switching to a PureAire non-depleting, zirconium oxide sensor will save you time and money, while ensuring the safety of your workers and facility.
Since PureAire monitors do not need to be calibrated, you do not need to purchase calibration gas.
Electrochemical sensors offered by other gas detection companies lose accuracy over time and must be calibrated. Calibration recharges and resets the monitor to get an accurate reading. It is important to note that an electrochemical sensor can only be calibrated a finite number of times before it must be discarded.
PureAire’s non-depleting zirconium oxide sensor will not experience drift. Oxygen sensors from PureAire will provide long lasting, reliable, and accurate monitoring for an average of10+ years.
To ensure safety, PureAire generally recommends that one monitor be installed for approximately every 400 square feet of your facility’s space. However, since cryogenic gases, such as argon, helium, and nitrogen, are unpredictable, we encourage you to contact PureAire for additional guidance specific to your needs.
In most circumstances, PureAire recommends that oxygen monitors be installed 3-5 feet away from gas cylinders or cryogenic gas lines. To enable employees to see the monitor display and verify its performance, PureAire recommends mounting an oxygen monitor 3-5 feet off the ground.
There are other options for mounting an oxygen monitor. For instance, PureAire sensors can sample the air from up to 100 feet away, or be installed within a glovebox, freezer, sealed chamber, or even underground. PureAire monitors can also work in environments that require KF-25 flanges, as well as in nitrogen/argon enriched environments.
PureAire’s Sample Draw Monitors pull a sample flow at a rate of 250 ccs per minute. We recommend using 1/4” OD x 3/16” ID polypropylene sample tubing. Using this internal tubing dimension, to calculate transport (response) time, add 2 seconds per foot of sample tubing. For example, if the sample tube is 10 feet long, the initial response time would be 20 seconds (10ft x 2seconds=20seconds) at 15 feet the response time would be 30 seconds (15ft x 2seconds=30seconds), etc.
The response time when using the entire 100 feet of sample tube will take 3.5 minutes (100ft x 2seconds=200seconds or 3.5minutes) for the sample to reach the monitor.
