The received data are displayed on the display after 5 sec of the measuring in the form of numbers.
As for Pulse oximeter ChoiceMMed MD300C19 it was made in white and blue in a miniature case in the form of a clothespin.
After 2-7 seconds when you put the device on the finger, the result will be displayed on the color LED display with large symbols.
Blood oxygen saturation is determined in the range of 35-99%, and heart rate – in the range of 35-250 beats per minute.
The model is equipped with a customizable sound alert function – an acoustic signal is heard if the value of any parameter exceeds the set limits.
The ChoiceMMed MD300C12 pulse oximeter has 2 AAA batteries and is equipped with an automatic shut-off function.
A neck strap is included in the delivery set so that the device is always at hand.

Zacurate vs Choicemmed Working Method
|Working Method||Red blood cells (erythrocytes) contain the protein hemoglobin, which carries oxygen.
The principle of operation of a pulse oximeter is based on the difference in the ability to absorb red light by hemoglobin saturated with oxygen and insufficiently saturated with it.
The light source is located on one side of the device, and the receiving sensor is located on the other side. When you put your finger in the pulse oximeter, it sends light waves through your tissues.
Hemoglobin with oxygen and hemoglobin without oxygen absorb light waves of different wavelengths. The pulse oximeter analyzes the amount of light transmitted and translates the information into numbers.
So you find out how many percent of hemoglobin is saturated with oxygen.
|The principle of operation of the MD 300C12 pulse oximeter is based on the fact that oxyhemoglobin (hemoglobin saturated with oxygen, HbO₂) and deoxyhemoglobin (oxyhemoglobin that has given oxygen to the cells of the body, HbR) present in the blood have different absorption of light in the red and infrared regions of the spectrum.
Oxyhemoglobin HbO₂ predominantly absorbs light in the infrared region of the spectrum (λ=905 nm), and deoxyhemoglobin absorbs light in the red region of the spectrum (λ=660 nm).
At the bottom of the device, two LEDs are built in, which alternately emit light in the red and infrared regions of the spectrum. In the upper part there is a sensor with a photosensitive element that registers the radiation that has passed through the finger.
By analyzing the absorption of radiation with red and infrared wavelengths, the saturation value is calculated.
The value of the pulse rate is obtained by analyzing the pulse wave characterizing the heart rate over time.
The results of the analysis are displayed in the form of saturation level and pulse rate values.
As you already know from previous articles, it is important to choose ONLY height quality medical devices. The quality of the device plays an important role – it is better to choose well-known brands and check documents and FDA and other certificates.
It is foolish to expect that a device from an unknown manufacturer, bought for two dollars on the Internet, will work like a professional one. Therefore, when buying a device, try to choose devices of well-known brands.
As for today’s 2 products I would definitely recommend both of them. These devices are not simple devices from the Internet that will be broken in several weeks, although they are not expensive.
These are high-quality devices from well-known brands with high work performance and accurate measurements that make them reliable.
But if you need the best pulse oximeter at the market then pay attention to the Pulse X Pro.
