The best pulse oximeter is a unit that delivers accurate results, right? But the device should also be durable, something that you can use for a long, long time.

In that case, allow me to discuss the features of the Easy@Home Deluxe Fingertip Pulse Oximeter. It gives you the opportunity to check your pulse rate along with SpO2 quickly. All you need to do is push a single button. And it provides the most accurate readings. These are present in the form of numbers.

Along with bar graph and waveform graph (known as Plethysmograph)! You should know that the graph offers visual indications. Of weak and irregular heartbeat! And also of incorrect readings!

On top of that, the bright OLED display rotates in 4 different directions. So you get many angles to view the results from. What’s more is that the Easy@HomeOximeter contains exceptional AAA batteries.

So you can rely on this FDA-approved pulse oximeter. For both performance and durability.

Measuring pulse and the level of oxygen in your blood is a quick and easy task. Especially when using the Easy@Home Deluxe Fingertip Pulse Oximeter. It fits both adults and children. And the readings that you get are accurate and visible from any angle.

Also, the quality of construction is equally remarkable. Not many oximeters have the ability to deliver this kind of long-lasting value.

Unfortunately, the device’s battery plate is a bit troublesome. It is prone to becoming loose or coming off more than you can imagine. So replacing those batteries might not be such a pleasant experience.

  • The Easy@Homeoximeter offers simple, intuitive operation.
  • Battery longevity is pretty impressive.
  • The display provides large numbers and letters for easy reading.
  • Inconsistent readings are quite common.

It shows you real-time readings for blood oxygen. Along with an invaluable pleth bar graph for the pulse rate! And the accuracy of both the readings is quite remarkable.

All you have to do to gain access to such convenience is press a button.

Overall, easy usability is a big part of the picture. As for the batteries, they offer an impressive 30-hour life. And that too with a useful automatic shut off component! So every little aspect is well taken care of. Especially when talking about performance!

The LED display of oximeters is among the most important parts, right? Without a bright display, you can’t use the device under low light conditions.

With that in mind, you’ll appreciate the display of the Santamedical Deluxe SM-110 Oximeter. From bright sunlight to dark surroundings, the tiny machine works exceptionally well in any setting.

Now for the downside, the spring closure of the finger is quite inadequate. While using, it might fall off your finger when inverted. So this can prove to be a nuisance during operation.

  • The Santamedicaloximeter responds quickly.
  • The readings are consistently accurate.
  • It includes a sturdy carry case.
  • Durability is weak.
  • Spring closure for the finger offers poor performance.

And you don’t even have to worry about usability. As the device is easy and convenient to operate!

Let me highlight the most beneficial features in here. The Innovooximeter allows you to set limits for pressure and SpO2. And if these limits are crossed, the alarm does an excellent job of warning you.

On top of that, there’s the Perfusion Index and Plethysmograph. These give you accurate readings. Then come the adjustable brightness and multi-directional screen. For maximum convenience!

What more could you have asked for, right!

Sadly, the quality of the product is not all that impressive. Upon testing, I found the unit to be cheap, design-wise. And that can interfere with durability.

  • The Innovooximeter delivers fast, accurate readings.
  • The display offers clarity and plenty adjustable options.
  • Not suitable for medical applications.
  • It lacks a high-quality design/construction.

The on-the-go pulse and blood oxygen reading is the most appealing factor. And you can subject it to sports, professional, and home uses.

Allow me to use this section to highlight the AAA batteries of the device. It comes with two of them that run for as long as 40 hours. Despite continuous operation!

Plus, there’s the battery indicator to notify when it’s low. Also included is automatic shut off that contributes to further conserving power.

The major disappointment comes in the form of a reversed view in this case. The invaluable finger meter doesn’t face in your direction. And you might take some time to get used to that.

  • The CMS oximeter is highly accurate.
  • The spring hinge is adjustable to fit all sizes of fingers.
  • It includes a carry case.
  • Finger meter offers a reversed view.

  • It is lightweight and portable.
  • Inconsistency is not eliminated.

That is how it can monitor your pulse and SpO2 in the most precise manner. And the large, clear LED display presents those readings even under bright or low light.

The part that might discourage you from buying the product is this. The Concord Sapphire Fingertip Pulse Oximeter is not as sensitive as it should be.

Best Pulse Oximeter: Buyer’s Guide


It’s only in the recent years that the pulse oximeter device has become popular. Especially for home applications! It was quite prominent in the ‘80s. But now the useful tool has a more affordable price tag.

So what is the best pulse oximeter? It is a non-invasive, simple electronic piece of equipment that measures two things. The oxygen level in the body and your pulse rate!

You place the sensor either on the fingertip or earlobe. This sensor sends out 2 light streams; one red and the other infrared. And these lights get absorbed by both your deoxygenated blood and oxygenated blood.

Then, depending on the amount of hemoglobin absorption at the 2 different wavelengths in the bloodstream, the oximeter measures your oxygen level.

It goes without saying that our oxygen saturation varies. Common factors that tend to deliver inaccurate results are as follows.

  • Weak pulse
  • Cold hands
  • Acrylic nails/fingernail polish
  • Hand movements, etc.

If you’re a healthy person, you can expect a reading above 97 percent. It should never be less than 95 percent.

Now let’s talk about the benefits of using the best pulse oximeter.

Professional athletes and mountain climbers wear the device more than anybody else. The former requires it to track oxygen levels while performing the strenuous workout. And the latter use it to keep oxygen levels in check due to high-altitude climbing.

But the most important benefit relates to medical conditions, right?

When recovering from surgery or injury, the tool can be very useful. If you have a condition that affects your blood oxygen, then you need a device like this.

These conditions include heart failure, heart attack, lung cancer, anemia, pneumonia, and asthma. Along with COPD (chronic obtrusive pulmonary disease)!

Now that you know enough about what a pulse oximeter is and does, it’s time to move on. Let’s discuss the different types of models you get to choose from.

Different Types of Pulse Oximeters

Finger Oximeter

The finger oximeter is a portable device perfect for home applications. It has an alligator-shaped clip that you can attach to your finger or earlobe. And the thing passes infrared light through your veins.

To display deoxygenated and oxygenated blood cells. (Normal blood oxygen levels) But remember that the tool doesn’t show accurate readings if your finger or hand is cold.

Handheld Oximeter

Medical institutions and hospitals use the handheld version. Even home users find these types of pulse oximeters valuable.

The device consists of a cable that attaches the screen and the clip together. And the infrared does an excellent job of delivering accurate results. For proper diagnosis! You can even clip the tool to the toe during emergencies.

Wrist Oximeter

You wear it around your wrist; that’s the only difference. It provides the same accurate readings as any finger oximeter.

Fetal Oximeter

When you want to check your baby’s health during normal delivery, this is the pulse oximeter to use. The probe of the device is what you place on your baby’s head.

This way, a medical professional can be well prepared to take necessary steps if required.

Pediatric Oximeter

Such a device is suitable for the small fingers and toes of a baby. You can even wrap it around his/her ankles.
