Accuracy, Dependability and an Industry Leading Warranty - At a Lower Price!

"There are less expensive pulse oximeters out there but NONE are as accurate as the Nonin brand, period. I use the Nonin Pulse Oximeters in my medical practice exclusively and wouldn't even think of using another brand." --- Dr. Brent Blue

Getting a dependable pulse oximeter for use in the cockpit used to cost hundreds of dollars when Aeromedix first introduced the technology to general aviation over 10 years ago. With Nonin's introduction of the 9590 Onyx Vantage, that's no longer the case. You can now get a trustworthy self-contained fingertip pulse oximeter with a 4 year warranty for under $180! You don't have to settle for a cheap pulse oximeter that may break the first time it's dropped and/or give you erratic and unreliable oxygen saturation statistics. Small and lightweight, the 9590 can be carried in your pocket and will deliver your blood oxygen saturation within seconds.


With Dr. Blue on our staff, we are able to offer this prescription-only device to you without needing a trip to a physician. We write the prescription for you the same day you order.

What happened To The Nonin 9500 Onyx and 9550 Onyx II?
After over 10 years of service, Nonin decided that they can offer patients and medical personnel more for their money by incorporating the elements of what made the 9500 a great pulse oximeter with some of the more advanced features of the 9550 Onyx II. With the addition of a 4 year warranty and a lower price than the 9500 Onyx, the result became the 9590 Onyx Vantage. We think this is a great move on Nonin's part, and while we are sad to see such a successful product as the 9500 Onyx go, we are excited about what the 9590 offers customers in terms of accuracy, durability and value. We think you'll agree as well. As for the 9550 Onyx II, these will still be available to the US military but will no longer be available for public purchase.

Why Should I Fly with a Pulse Oximeter?
A good pulse oximeter makes it simple and easy to measure the concentration of oxygen in your blood. Knowing this important bit of information is really the first step in being aware of your body's oxygen needs, knowing when and how much supplemental oxygen to use, and catching the symptoms of altitude-induced hypoxia before it's too late. For over 10 years, Aeromedix has been introducing and promoting the use of pulse oximetry in aviation to give pilots (especially GA pilots) an added degree of safety when flying.

What About the Less Expensive Pulse Oximeters I See?
These days, the market is saturated with fingertip pulse oximeters, most of them coming from overseas. We at Aeromedix, however, have promoted the Nonin brand of oximeters because of their proven reliability and accuracy. We have seen time and time again that, as far as pulse oximeters go, it is truly a "get what you pay for" situation. Many of these cheaper units simply do not provide consistently accurate readings and many of them will break the first time they are dropped. Nonin oximeters, however, are made to last and their accuracy can only be matched by expensive hospital or laboratory units that cost hundreds or even thousands of dollars. Nonin has such a great track record of making a quality product that we regularly have customers who purchased a 9500 Onyx 10 or more years ago and are still using it! Even the US Military spotted quality in the Nonin name - the 9550 Onyx II is now sold exclusively to the military as it has been tested to perform even in the most demanding conditions.

Now Quality Is Within Reach
The 9590 Onyx Vantage makes getting a quality pulse oximeter more affordable than ever. At a price under $180, the 9590 will serve you and your passengers well for years to come, but won't break your wallet. The 9590 Onyx Vantage can only be sold with a medical perscription , but our own Dr. Blue can write a prescription for you, saving you a trip to the doctor. Don't take chances on your safety, get a pulse oximeter you can fly with and trust.
