FL330 Wearable Pulse Oximeter with Vibration Alarm, APP, and PC Software

$179.00 179.00

The FL330 Wrist Pulse Oximeter digitally monitors blood oxygen saturation levels and pulse rate. The device is worn on the user’s wrist with a secure adjustable wristband. The removable soft silicone ring sensor was designed to fit on any finger and allow for a wide range of motion.

The FL330 supports overnight continuous recording of blood oxygen saturation levels, heart rate, and movement. The adjustable vibration alert gently nudges the wearer to wake when the oximeter detects SpO2 levels below the user’s defined level. The vibration also alerts the wearer to adjust their position to reduce snoring, resulting in greater levels of oxygen intake. The backlit display reduces eye strain through the use of blue LEDs.

The monitor’s oval-shaped design and rounded edges won’t cause discomfort to the user when worn overnight or while exercising. The built-in battery is rechargeable via a standard USB connection. The lithium-ion battery lasts for up to 16 hours of continuous recording.

Measurement history is stored directly on this wrist oxygen monitor’s internal memory. The free PC software generates sleep reports that can be exported and saved in PDF or CSV formats. The reports can be easily shared with health professionals or friends! The software is ONLY compatible with Windows PC systems (not compatible with Mac). The free iOS and Android app includes features for sharing overnight blood oxygen trend reports and displaying real-time measurement information from the FL330 oxygen meter.

This FL330 Pulse Oximeter is much easier to use than a conventional fingertip oxygen monitor when exercising. When hiking/walking/exercising, a 10 second rest is all that is needed for a measurement. If oxygen levels are not normal, the user can either rest for a few minutes or continue moving if their oxygen levels are normal.


Smart Vibration and Ring Sensor

The FL330 can detect changes in O2 levels and activate a vibration when blood oxygen levels lower than the threshold range are detected, preventing a low-oxygen status. FL330 cannot be used for sleep breathing problems.

Patented Ring Sensor

The FL330 was designed for comfort and continuous use. The patented ring sensor allows you to wear your device wherever you are, and it will never fall off from your fingers, even while walking. The FL330 doesn't provide readings during sport activities.

Blood Oxygen Saturation Report

Graphics for the FL330 show O2 saturation & Heart Rate trends that are useful for personal health tracking.

The report cannot show oxygen changes under a few seconds in length, therefore it can't be used for sleep breathing problems.


Continuous Monitoring for Oxygen Level & Heart Rate

Continuous monitoring and recording blood oxygen levels, heart rate, and motion. The high-efficiency Li-ion battery lasts for up to 16 hours of continuous recording.

Customer Reviews

Based on 5 reviews
atypical usb

The finger reporter seems fragile. The USB is atypical what type is it? Why not USB-C

Excellent product

Please inform the folks at pulseoximeter.com that I bought this from you guys, so I can get a refund from them for the crappy product THEY sold me.

A must have for stay-at-home Covid patients

Great way to monitor O2 and pulse rate continuously during this pandemic. Provides data needed to decide it it's time to go the the ER.


Product working great!


Would recommend this devise, and have recommended this devise to others. The graphic printouts have embarrassed numerous Medical Doctors identifying just how wrong their medical opinions are.
