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

$158.00 158.00

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.


FL330 sensor FL330 report

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.

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.

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

FL330 Wearable Pulse Oximeter Review

So far, so good. It loses the reading occasionally (loses contact ?) but it doesn't last long and comes back on. But ocerall I am satisfied with its performance.

Charles Smith
Excellent choice

This device is incredible. The only time I don’t wear it, is when it is charging. The vibration gets my attention without affecting others near. When I am sleeping, the vibration wakes me without waking my wife. My daughter is a PA. She can check the history and feel confident that I am in control. The best insurance policy Iever bought.

so far I am happy with it, Bill

Good for night time low 02

Bought for my husband who’s O2 drops at night due to light snoring. The vibration is enough to wake him up so he can reposition. Also useful to track bradycardia that occurs at night.

great little piece of equipment

This device works and is very helpful for someone like me who likes to be very independent whenever possible from doctors.
It enables me to see what is going on and then go to medical professionals for a consultation.
I highly recommend it.
The only problem I am having is finding out where to get another charger, but I contacted customer service
and as they are usually very responsive I expect an answer soon!
