ChoiceMMed vs Contec Top Pulse Oximeters

It is quite a well-known medical equipment manufacturer that was founded in 1993 in Beijing, China.

The disadvantage of Choice med pulse oximeter is that  it does not have   FDA approval.

The Company produces a huge variety of medical devices with innovative technologies.

The Company is established in Beijing, China.

Oxygen saturation (SpO2) measurement range from 70% to 100%;

Saturation measurement error no more than 2%;

 Measurement range of pulse rate (PR), beats/min – from 30 to 250;

Error of measurement of pulse no more than 2 beats/min;

Operating time from one set of batteries – more than 30 hours;

Admissible circle of a finger for measurement: 20 – 75 mm

SpO2 display range– 0% – 99%

SpO2 measurement range– 70% – 99% (± 3%)

Heart rate display -30 – 250 bpm

Pulse measurement range– 30 – 250 (± 2 bpm)

The display shows SpO2, pulse rate as a bar graph, battery capacity

Operation- 5°C – 40°C, humidity up to 80%

•  Large Led Display
•  Can choose one of 10 levels of display illumination 
• Creates and display a pulse histogram
• The gadget consumes a minimum of energy, so it does not require frequent replacement of batteries.

Comes with a handy storage case and cord.

The device was additionally packed in a plastic bag.

Has only one button – inclusion.

It turns off automatically quite quickly if it does not measure.

The LCD displays two indicators – the pulse (upper line) and the level of oxygen in the blood (lower line).

The measurement range for SpO2 is from 0% to 100%, but as the doctor told me, the best indicator would be 98%.

For the pulse, the range here is from 30 to 250 beats per minute.

The measurement accuracy, according to the manufacturer, is +/- 2% and +/- 2 bpm.

During the illness, the pulse rate for all of my family members was quite high, I even doubted the correctness of the measurement.

But later I thought of comparing it with the pulse that the fitness bracelet considers for me, and the results almost coincided.

Well, to be honest, I did not find any information about Germany. It’s all about China.

A lanyard is included.

The device itself is small in size and light in weight. The finger does not pull.

 I tried to measure on different fingers, periodically changed hands, but the indicators are the same everywhere.

In addition, it is not recommended to measure in the presence of varnish and gel polish.

I wear ordinary nail varnish, but personally for me, this does not affect the saturation indicators – I tried to carry out this manipulation on clean nails.

As for gel polish, I don’t know – I can’t say personally.

But many of my friends also measure with gel polish – so far everything is fine.

But this is as long as you are healthy and there are no complaints. In case of illness, it is better, of course, to adhere to the rules so as not to miss complications.

The device can set a different level of display brightness (there are already 10 of them).

The default is level 4. I tried all the levels – in principle, there is not much difference.

And the batteries save a lot. Came back again in level 4.
