For whom is the Nonin Onyx Vantage 9590 suitable?

The Nonin Onyx Vantage 9590 finger pulse oximeter is suitable for adults and children with a finger diameter from 0.8 to 2.5 centimeters. It is also suitable for people with a low oxygen saturation, and for people with a dark skin color (who have a lot of pigment in their skin).

Extremely accurate measurements guaranteed with PureSAT^® Technology

This clinically tested Nonin pulse oximeter provides very accurate measurements of the oxygen saturation level (SpO2) and pulse rate. The accuracy of the high-quality PureLight^® LED sensors has been scientifically proven (for people suffering from a low oxygen level). The device is equipped with patented PureSAT^® Technology that guarantees reliable results, even in the case of oxygen desaturation. Research shows that the Onyx Vantage 9590 remains reliable when the user’s oxygen saturation drops during a measurement.¹ The Nonin Onyx pulse oximeter displayed the saturation drop correctly, while other pulse oximeters incorrectly displayed a high oxygen saturation level.

LED indicator for even more reliability

Thanks to the bright LED display you can easily read your oxygen saturation and pulse rate. From any angle, day or night: the Onyx Vantage 9590 will help you out! When using the device, a three-colour LED indicator lights up at the bottom of the display. The colour indicates the reliability of the measurement. With a green light the measurement signal is good, with an orange light it is marginal and with a red light it is weak. You should move as little as possible during the measurement and, if necessary, remove your finger from the Nonin pulse oximeter and put it back in.

Automatic switching (on/off function)

The Nonin Onyx Vantage 9590 is fast, efficient and easy to operate, without any buttons. The pulse oximeter automatically turns on when it detects your finger, thumb or toe. When removed, the oximeter turns off automatically. The device is thus economical: 2 AAA batteries provide up to 6000 spot checks.

Tip: for best results, keep the pulse oximeter at heart or chest level.
