It is important for all oxygen patients to monitor their oxygen levels. The 9500 is the smallest and easiest unit to use for monitoring of oxygen levels. It is fully automatic, easy to read, and extremely accurate. The unit is powered by two ordinary AAA alkaline batteries and has a great instant-on feature: insert your finger and it turns on automatically...remove your finger and it turns itself off. ----- Dr. Brent Blue

Need Additional Functionality?
The Nonin 9500 is a great tool for most home users who need accurate pulse oximeter information without the full capabilities of other clinical-grade equipment. The principal shortcoming of the Onyx (compared to Nonin's higher-priced models) is that it cannot use a remote sensor, making continuous monitoring something the 9500 is not well suited for. Also, it has no alarm, memory, or the ability to interface with a printer or PC. If you are looking for these features, consider the Nonin Onyx II 9560, PalmSAT 2500, or the WristOx 3150. Most home users don't need these features however, and it is no surprise that the Onyx, with it's quality and accuracy, is by far our best-selling pulse oximeter.
