Cheap portable colorful finger pulse oximeter

‍

finger pulse oximeter Main Functions

1.Easy operation, portable with lanyard

2.Clear display: Dual-color OLED display (blue and yellow) can be changed with four direction while press the silicon button, Screen definition: 128*64;

3.Display parameters: SpO2 value, Pulse rate value, bar graph, Pulse waveform, pulse mark, battery volume;

4.Pulse synchronization function. The pulse waveform, pulse mark, and bar graph are synchronous with the pulse beep;

5.Pulse Beep function. The pulse beep is synchronous with the pulse and can be on/off by press key;

6.Threshold Alarm: When the measurement result is out of the pre-setting threshold, the beep will alarm and sparkle;

7.Real time voltage indication: voltage indicator always appears and informs the users to replace the new battery;

8.Auto power off function: It will automatically power off within 8 seconds if the finger falls out of probe.

finger pulse oximeter Performance Index

1.SpO2 Measuring Range: 0%~100%, (the resolution is 1%).
Accuracy: 70%~100%:±2%, below 70% unspecified.

2.PR Measuring Range: 30bpm~250bpm, (the resolution is 1bpm)
