FL320 Wrist Pulse Oximeter for Sleep and Fitness - SPO2 & Heart Rate Recorder with Vibration Alerts

$179.00 179.00

The FL320 Wrist Pulse Oximeter utilizes a modern smart-band design with SpO2/pulse rate reading, step counting, a digital clock, and mobile app integration. This oximeter is light and compact to provide comfortable monitoring during sleep or exercise. Unlike other wrist-based pulse oximeters, the wired thumb sensor frees the wearer’s fingers for movement while recording. Detailed reference and reporting functions are available within the free O2 Vibe mobile app (available on the Apple App Store and Google Play Store) that syncs with your monitor’s data history.

Overnight sleep tracking in the FL320 includes a vibration alert system that lightly wakes the wearer if their oxygen levels fall below the set threshold range (between 90-95%). The wrist pulse oximeter vibrates at a low volume to avoid disturbing others and includes settings for disabling the alert function. This vibration alert system reduces the risk of low blood oxygenation and related side effects going unnoticed. The oximeter can continuously monitor up to 20 hours of overnight sleep activity or 12 hours during the day.

This portable oximeter maximizes fitness regimens by tracking blood oxygen saturation and pulse rate during exercise. When enabled, the monitor automatically reminds users to keep moving at intervals throughout the day for maintaining daily step goals. The FL320 uses soft silicone materials that won’t cause discomfort when continuously wearing the device.

Every required accessory is included: device, one ring sensor, one USB charging cable, one quick start guide

This FL320 monitor is not a medical device. The built in rechargeable battery charges via micro USB (cord included).

Wrist Pulse Oximeter

Have used this on several occasions; works as advertised. Comparison with a clinical device suggests the wrist pulse oximeter is accurate. Would buy again and recommend without reservation. Note that micro D USB port cover will easily be lost-I tethered mine with thin nylon multifilament string to the oximeter..
