Nonin Onyx II 9550 Fingertip Pulse Oximeter

The Nonin Onyx II 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 II Nonin 9550 offers many improvements over the original 9500 design, including approximately 800 more spot checks for each batch of two AAA batteries.

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.

The portability and functionality of the Onyx II make it a valuable tool in any situation where a fast and accurate reading of blood oxygen saturation and pulse rate are needed. Never search for a pulse oximeter or sensor again.

• Small & Lightweight – Carry the Onyx II anywhere on a lanyard, in a carrying case or in your pocket. It weighs less than 2 oz.
• Enhanced Design – Smaller size with an enclosed spring and easier battery access.
• Large Bright LED Display – SpO2 and Pulse Rate that can be read from any angle, day or night.
• Pulse Quality Indicator – Brilliant, easy-to-see LED provides a quick and accurate assessment of patient readings.
• Pediatric to Adult Finger Sizes – Accommodates a wide range of finger thicknesses, 8 to 26 mm (0.3 to 1.0 inch).
• Automatic On/Off – Auto turn on and off with finger insertion and removal.
• Energy Efficient – A new turn-off mechanism allows two AAA batteries to provide approximately 2,500 spot-checks or 21 hours of continuous operation.

The Nonin Onyx II 9550 is so durable and reliable that the Military accepts nothing but the Nonin! Rugged enough to be used in the most demanding situations. That’s why it carries the US Army and US Air Force aeromedical certification for use in helicopters.
