Nonin Onyx 9550 ® Professional Quality Finger Oxygen Meter

The Nonin Onyx 9550 was created as an upgrade for the popular 9500. This digital fingertip pulse oximeter makes it possible for anyone to carefully monitor their blood saturation levels and pulse rate. The Onyx 2 Nonin 9550 offers many improvements over the original 9500 design, including approximately 800 more spot checks for each batch of two AAA batteries.

This unit is also certified for usage in helicopters by the US Air Force and Army due to its proven durability, and it includes a bright LED screen so that you can access your readings from any angle. Keeping your oxygen levels and pulse rate in line are important for proper health — especially in the military - and this unit will help alert you to any potential problems before they become a major issue.
