Pulse oximetry is the simplest and most affordable method for monitoring blood oxygen saturation. Previously, only blood gas analysis was used for this.
However, the use of stationary and portable pulse oximeters makes it possible in most cases to avoid the need to conduct laboratory tests and receive diagnostic results immediately on the screen.
The pulse oximeter has a simple operating principle and high performance.
Today Let’s look at the following Pulse Oximeters: Facelake 400 FL vs Zacurate 500 DL…
Unfortunately none of them made it to my top #1 Oximeter list.
The best oximeter in the market right now is Pulse X Pro, Check out my full review here.
Oxiline Pulse X Pro is currently the best fingertip pulse oximeter on the market with the easiest adjustment to your smartphone.
It can measure your Saturation Measurements and Perfusion Index in several seconds with 98% accuracy!

Facelake vs Zacurate Pulse Oximeters
Zacurate 500 dl Pulse Oximeter:
Despite the fact that this device is not medical, thanks to ultra-sensitive sensors, they show high accuracy and guarantee quality.
Model 500 dl will provide an accurate result in a few seconds.
The color display will show not only the saturation percentage and pulse rate, but also a histogram and pulse graph, as well as a perfusion index.
Facelake FL 400 Pulse Oximeter
The Facelake FL400 fingertip pulse oximeter is a light and compact device. It is used for measuring pulse rate and SpO2.
There is a vinyl sensor for an instant vital measurement reading.
After a single press of the device’s primary button, the oximeter displays results on its large digital LED display.
The advantage of this pulse oximeter is that The FL400 is universal for all finger types which means that it accommodates different finger shapes and sizes.
The pulse oximeter has an auto shut-down function, low battery indicator, and a heart rate bar graph built-in to the device.
Facelake vs Zacurate Pulse Oximeters Technical Details
|Model/Question||Facelake Fl400||Zacurate 500dl|
|What does it determine?||It is used to accurately check the SPO2 (blood oxygen saturation levels) and pulse rate of a patient.||Check SPO2 and heart rate…|
|How Fast does it show saturation?||It determines your SPO2 and pulse rate in 10 seconds…||It determines your SPO2 and pulse rate in 6-7 seconds…|
|Where Can I get It?|
|For Whom Is This?||It is used for sports and aviation only and is not considered a medical device.||It is made for professional sportsmen and for mass screening examinations to use at home for self-monitoring of saturation of patients in various pathological conditions that cause hypoxia.|
|Protection||Double Plastic Shields Protection.||Double Plastic Shields + Silicon Cover Protection that protects it from all the damages.|
|Certifications||Manufactured according to CE and FDA standards for pulse oximeters.||The Advantage of Zacurate pulse oximeter is manufactured according to the CE and FDA standards.|
|Guarantee||Comes with a no-hassle money-back guarantee and one year warranty.||Comes with 1 year guarantee.|
This pulse oximeter can often cease to function after a year, so it makes the warranty useless.
|Batteries||Equipped with two AAA batteries with 30+ hours of continuous monitoring on one set of batteries||Equipped with one set of two AAA batteries keeps the device powered for up to 30 hours of average usage.|
How Does Facelake vs Zacurate Work?
|The Question||Zacurate 500 Dl||Facelake FL 400|
|How Does it Work?||The sensor with LEDs is superimposed on the finger. |
When light passes through the blood and soft tissues, it is partially absorbed, which makes it possible to determine the oxygen content in the blood.
The received data are displayed on the display of the device in the form of numbers
|The pulse oximeter uses two photon optical elements and two radiation sources.|
They operate in the range of 660 – 940 nm. The arteries are constantly pulsing, so most saturation measurements are constant.
The device constantly measures the difference between signal absorption in the red and infrared regions.
As it passes through the tissues, the blood pulsates.
The device calculates the number of these vibrations by counting the pulse.
Personal Experience of Facelake vs Zacurate
|Facelake FL400||Zacurate 500 DL|
|I chose it because I liked the price and the presence of a certificate.|
Packing – in soft rubber foam and a box.
I used it for around 10 days.
So far, no complaints.
Compared with devices from doctors, the testimony converges.
Moreover, some doctors use exactly this model, although it is not a medical device.
Packing – in soft foam rubber and a box.
It is a good product with proven effectiveness, and has all the necessary documentation.
The black-and-white digital screen clearly displays all the necessary data – the pulse rate, as well as the level of blood oxygen saturation (SpO2).
There is also a battery indicator on the display.
Other Pulse oximeters with a bright OLED display are more expensive.
Here are some moments what I did not like
The device is VERY sensitive to the position in space and on the arm – if something goes wrong, it immediately turns off
– Even if it seems to have started working and showing something – these indications can at any moment start to slow down, change in different directions, and so on until the shutdown (pulse indicators can also jump with a difference of up to 20 points)…
|Zacurate 500 DL Pulse Oximeter got the best reviews from consumers which makes it a very reliable pick. |
Zacurate 500 DL Pulse Oximeter is considered to be a professional pulse oximeter that can detect Sp02 level of up to 100%.
As for my experience, this pulse oximeter is surprisingly not bad at all. When I received it, my husband and I were surprised by the quite good quality. The plastic is dense, smooth, without notches and burrs, not flimsy, without foreign odors.
You take it in your hands and it’s an even nicer feeling of expensive material. Moderately hefty.
When you start using it, the device first “thinks”. Sometimes a little longer, sometimes a little faster, but not for long.
I timed the stopwatch to see how much it measured. It was less than 6 seconds.
I don’t like the indicators on the device that can change places, which sometimes almost bring me to a heart attack. I’m getting used to the fact that the oxygen indicator shows at the top of the screen, and the pulse at the bottom. And sometimes this position changes, and the pulse becomes at the top, and SPO2 at the bottom.
Both Pulse Oximeters are not recommended for medical purposes, they are used only for sports and aviation.
Both of them were made for professional sportsmen and for mass screening examinations to use at home for self-monitoring of saturation of patients in various pathological conditions that cause hypoxia.
By comparing these 2 oximeters I would choose FL400, it is more new and more updated technology that allows me to get quick, precisely accurate readings.
The device is the perfect use for all ages and its lightweight and compact structure makes it an easy-to-carry device universally accommodating different finger shapes and sizes.
Why Does My Pulse Oximeter Show Me Wrong Results?
- The device is fixed too tightly or loosely.
- There is varnish on the nails;
- During the measurement of saturation, the person moves;
- There are scars, burns and other injuries on the fingers;
- There is too bright a light source near the device;
- Taking measurements from wet or frozen fingers.
What Oxygen Saturation Can Cause?
- Redness of tissues, especially lips;
- State of nervousness;
