Description
Quick answer: The Nonin WristOx2 3150 BLE is a clinical-grade, wrist-worn pulse oximeter for continuous SpO₂ and pulse-rate monitoring — ideal for overnight oximetry, sleep studies, homecare, and ambulatory use. Worn like a watch with a finger sensor, it uses Nonin’s PureSAT® technology for accurate readings even in low perfusion or motion, records up to 1,080 hours of data, and transfers it wirelessly via Bluetooth® Low Energy to nVISION® software, NoninConnect apps, or the Nonin Health® cloud platform. Made in the USA with a 3-year warranty.
What is the WristOx2 3150 BLE for?
Built for extended, reliable monitoring rather than quick spot-checks, the WristOx2 3150 records oxygen saturation and pulse rate over long sessions and stores the data for review. It’s designed for accurate SpO₂ and pulse-rate monitoring in sleep labs, homecare, and ambulatory settings using PureSAT technology, and is suitable for adults and pediatrics over 30 lbs (14 kg). Common uses include overnight oximetry, sleep-apnea screening, home oxygen assessment, six-minute walk tests, and non-invasive ventilation (NIV) monitoring.
Key features
- Wrist-worn, watch-style design — lightweight (~70 g) and comfortable for long sessions.
- PureSAT® technology — accurate readings, even in low perfusion and motion.

Frequently asked questions
What is this oximeter used for?
Continuous SpO₂ and pulse-rate monitoring — especially overnight oximetry, sleep studies, walk tests, and homecare.
What is the Bluetooth LE used for?
Wireless transfer of recorded data to nVISION software, NoninConnect apps, or the Nonin Health cloud platform for analysis and reporting.
How long does the battery last?
About 48 hours without Bluetooth, or roughly 24 hours with Bluetooth active, on 2 AAA batteries.
Which sensors does it use?
WristOx2-series sensors (WO2 connector) only — reusable soft sensors (S/M/L) or single-use cloth sensors.
Is it good for sleep studies?
Yes — the wrist-worn design and up to 1,080 hours of memory make it well suited to overnight and multi-night recording.
Can I get it delivered in Brooklyn or shipped nationwide?
Yes — Stark Medical Supplies offers local pickup and delivery in Brooklyn and across NYC, plus USPS shipping throughout the continental U.S.
