CMS50D+ OLED Fingertip Pulse Oximeter:

The CMS50D+ has a colour, multi-direction LCD screen for displaying oxygen saturation (SpO2) and pulse rate, which can be displayed in numerical, waveform, or graph formats. This advanced pulse oximeter also allows for the setting of alarms, can emit a pulse rate sound, and data can be stored and uploaded to your computer.


Dimensions: 58.5(L) × 31(W) × 32 (H) mm.
Weight: About 50g (with batteries inserted).


CE and FDA certified.

Technical specifications:

Main Performance:

  • SpO2 value display.
  • Pulse rate value display, Bar graph display.
  • Pulse waveform display.
  • Low-voltage indication: Low-voltage indicator appears before working abnormally which is due to low-voltage.
  • Display direction can be changed automatically, easy to view.
  • The product will enter standby mode when no signal is in the product within 5 seconds.
  • A pulse rate sound indication.
  • With alarm function.
  • With the SpO2 value and pulse rate value of storage, the stored data can be uploaded to computers.
  • Data can be transmitted to computers.

Measurement of SpO2:

Measuring range: 0% ~ 100%.

Accuracy: When the SpO2 measuring range is 70% ~ 100%, the permission of absolute error is ±2%; below 70% unspecified.

Measurement of Pulse Rate:

Measuring range: 30bpm ~ 250bpm.

Accuracy: ±2bpm (beats per minute) or ±2% (select larger).


SpO2: 1%, Pulse rate 1bpm. (Beats per minute)

Measurement Performance in Weak Filling Condition:

SpO2 and pulse rate can be shown correctly when the pulse-filling ratio is 0.4%. SpO2 error is ±4%, and pulse rate error is ±2bpm (beats per minute) or ±2% (select larger).

Resistance to Surrounding Light:

The deviation between the value measured in the condition of man-made light or indoor natural light and that of a darkroom is less than ±1%.

Power Supply Requirement:

2.6V DC ~ 3.6V DC.
