Nonin WristOx2 Model 3150 Pulse Oximeter

Nonin WristOx2 Model 3150 Pulse Oximeter offers continuous SpO2 and pulse rate tracking in a lightweight, wrist-worn design, making it ideal for users with respiratory conditions or those requiring regular oxygen monitoring. The compact unit can be worn comfortably throughout the day and during movement, offering flexibility without interrupting daily routines.

Engineered for low perfusion and motion tolerance, the device delivers fast, accurate readings in real-world conditions—whether during rest, activity, or sleep. It supports up to 1,080 hours of data storage, which can be exported through USB connection to compatible data management software for trend analysis and clinician review.

From home care to ambulatory monitoring, the Nonin 3150 WristOx2 Oximeter provides a durable, wearable solution for long-term health tracking. Its discreet profile and dependable performance make it a trusted option for users who value comfort, reliability, and remote access to their oxygen saturation data.

The Nonin WristOx2 display offers three modes depending on usage. In full display mode, the screen shows SpO2, pulse rate, an animated pulse strength indicator, and battery life. Partial display mode removes the pulse rate, showing only the battery indicator and pulse strength animation. When connected to nVISION software, the memory volume mode displays the total hours and minutes of recorded data, along with the battery and pulse strength indicators.

The soft sensor is placed gently over one finger as it carefully reads oxygen levels, making it ideal for performing overnight oximetry tests. The sensor can be added on or removed as needed, depending on whether the oximeter is being used for oximetry or pulse readings.
