2. Wellue Oxyfit Finger Pulse Oximeter
When considering what is my 2nd best finger pulse oximeter for you, the Wellue Oxyfit Finger Pulse Oximeter is almost the best overall option with a lot of features.
What makes this pulse oximeter one-of-a-kind is the way that it fits over your finger. It has a soft chamber with a duckbill sensor that you slide your finger into.
This design doesn’t match any other fingertip pulse oximeter. It provides ultimate comfort with its soft material and only applies little pressure on your fingertip.
I also think that this design helps to ensure your finger stays correctly positioned over the sensor to obtain your readings.
With pulse oximeters that clip over the finger, you have to be much more careful about placing it correctly on your finger.
The Wellue Oxyfit measures SpO2, pulse rate, perfusion index, and motion. It measures SpO2 within the range of 70-100% and pulse rate within the range of 30-250 beats per minute (bpm).
What’s also great about this pulse oximeter is that you can use it for spot checks (or take a single measurement), and you can also use it for continuous monitoring.
Furthermore, the Wellue Oxyfit also has an alarm that tells you when your SpO2 or pulse rate are abnormal.
You can set the limits yourself for SpO2 and pulse rate, and when your readings go outside of these limits, the sound alarm will go off in addition to a notice on the display.
Finally, this is the only finger pulse oximeter reviewed here that has a rechargeable battery. This lithium battery boasts a battery of 12-14 hours.
3. Zacurate Pro Series 500DL Finger Pulse Oximeter
The Zacurate Pro Series 500DL Finger Pulse Oximeter is the cheapest option with all of the important features.
This pulse oximeter clips over your finger to take your readings. It measures SpO2 and pulse rate but not perfusion index.
It measures SpO2 up to 100% and pulse rate within the range of 0-250 bpm. Also, it obtains readings even if your blood perfusion index is as low as 0.2%, which means that this is a pretty accurate device.
You can use this pulse oximeter for spot check, but it doesn’t have the capability to use it for continuous monitoring.
4. Wellue OxySmart Finger Pulse Oximeter
The Wellue OxySmart Finger Pulse Oximeter is an excellent option as it provides good value when considering its cost and features.
This pulse oximeter has the standard fingertip clip design to obtain readings.
It measures SpO2, pulse rate, and perfusion index. The range of SpO2 it can measure is 70-100%, and the range of pulse rate it can measure is 30-240 bpm.
Like the Wellue Oxyfit, you can conduct spot checks or continuous monitoring with this device.
Also like the Wellue Oxyfit, the Wellue OxySmart also has an alarm that tells you when your SpO2 or pulse rate are abnormal.
You can set the limits yourself for SpO2 and pulse rate, and when your readings go outside of these limits, the sound alarm will go off in addition to a notice on the display.
Unlike the WellueOxyfit, however, the WellueOxySmart doesn’t have a rechargeable battery. But it does require two AAA batteries.
5. Wellue FS20F Finger Pulse Oximeter
The Wellue FS20F Finger Pulse Oximeter is also a great option.
This pulse oximeter has the standard fingertip clip design to obtain readings. It measures SpO2 and pulse rate but not perfusion index.
The range of SpO2 it can measure is approximately 70-99%, and the range of pulse rate it can measure is approximately 25-250 bpm.
The fact that this device doesn’t measure SpO2 up to 100% makes it slightly inferior to the other devices listed here.
Like the other two Wellue finger pulse oximeters listed here, you can conduct spot checks or continuous monitoring with this device.
Furthermore, like the Wellue OxySmart, you can’t store data on the device, but it does have Bluetooth capability and the free mobile app to store your data on your phone.
The Wellue FS20F does also have an alarm for abnormal readings, however, the alarm is only a notice on the display and not a sound alarm.
Finally, this device requires two AAA batteries.
6. Innovo Deluxe iP900AP Finger Pulse Oximeter
The Innovo Deluxe iP900AP Finger Pulse Oximeter is another great option.
This pulse oximeter has the standard fingertip clip design to obtain readings. It measures SpO2, pulse rate, and perfusion index.
The range of SpO2 it can measure is 35-100%, and the range of pulse rate it can measure is 25-250 bpm.
You can conduct spot checks with this device but not continuous monitoring to collect longer-term data.
It also doesn’t have wireless connectivity via Bluetooth, a compatible mobile app for viewing data and analysis reports or a built-in memory.
Like a few of the other products reviewed here, the Innovo Deluxe iP900AP does have a sound alarm for abnormal readings.
You can set the parameters and change the settings for the alarm function based on your preferences.
Finally, this device takes two AAA batteries and has a pretty long battery life of 40 hours.
Finger Pulse Oximeter The Facts
Below I’ve outlined the key features for you to consider to help you decide which product is best for you.
Once you have a good understanding of these features, take a look at my table at the end of this section to help you compare the features across the products.
Perfusion Index
The perfusion index tells you the strength of your pulse, and a value of <0.2% means that either your finger is not properly positioned on the pulse oximeter sensor or your hands are too cold because of improper blood flow.
Design and Fit
This is important in that, with the fingertip pulse oximeters that clip over your finger, you have more of a chance of not positioning it correctly on the sensor to get accurate readings.
I therefore think the duckbill sensor with a chamber design is better in this regard.
Design and fit is also something to consider if comfort is an important factor for you, as fingertip clips can add more pressure on the finger. This is also important if you plan to use the finger pulse oximeter for continuous monitoring and would be wearing it for a longer period of time.
Continuous Monitoring and Data Storage
The continuous monitoring feature is important if you need or want to gather readings over a longer period of time. Data storage is also something to consider here.
Devices with built-in memory and/or phone storage would be important to have to store all of your data from your continuous monitoring readings.
Compatible Mobile App
This is a handy feature if you want to get the most out of your readings and look at trends, graphs, and detailed analysis.
With the reports generated in the mobile apps, you can get an even deeper understanding of what your measurements mean.
Alarm for Abnormal Readings
Alarms are especially helpful to let you know when your SpO2 or pulse rate aren’t within your normal range.
You can be warned when something doesn’t look right without having to watch the numbers closely while trying to remember what your normal ranges are.
Sound alarms are more convenient for this purpose compared to warnings that just pop on the display.
Battery Type
A rechargeable battery can be more convenient compared to having to remember to keep AAA batteries on hand and swap them out whenever the batteries are low.
Helpful Finger Pulse Oximeter Tips
- Low blood perfusion: If too low, this can affect accuracy of your readings. Check to make sure your finger is positioned properly.
Also, rub your hands together to improve blood flow and warm your fingers before taking your measurements. - Even spot checks need time to gather your reading: It takes about 10 seconds to collect your reading and some people may even require more time for the pulse oximeter to get to a point where it’s most sensitive.
In which case, you may even have to wait about 30 seconds for the readings to stabilize. - Stay still: Your hand should be still while taking a reading. This is because movements can make the device reset mid-reading.
- No nail polish or fake fingernails: These can cause false readings. Remove nail polish before taking a reading or try a different style of pulse oximeter such as the ones that are ring sensors.
My Final Thoughts
All of the finger pulse oximeters I tested here are excellent options you can trust to meet your pulse oximetry needs.
These range from my best overall pick, the Oxiline Pulse X Pro to the cheapest option with just the important features, the Zacurate Pro Series 500DL Finger Pulse Oximeter.
The key features I highlighted (including the design and fit, continuous monitoring capability, data storage, compatible mobile app, and sound alarm) are the most important things to consider to help you make your ultimate decision.
Hopefully this research and my detailed test here helped you decide what is the best finger pulse oximeter for you.
