Pulse Oximeter Fingertip Finger Pulse Oximeter

             Pulse Oximeter Fingertip 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.       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)
Accuracy:±2bpm or ±2% (select larger)       3.Measurement Performance in Weak Filling Condition: SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%; pulse rate error is ±2 Bpm or ±2% (select larger).       4.Resistance to surrounding light: The deviation between the value measured in the condition of man-made light or indoor natural light and that of darkroom is less than ±1%       5.Power Consumption: Less than 30mA
Voltage: DC 2.6V~3.6V
Power Supply: 1.5V (AAA size) alkaline batteries × 2   
Battery working hour: Theoretical number is 32 hours.
