| Count |
1 pulse oximeter |
| Includes |
Pulse Oximeter, Lanyard, Carrying Case, 2 AAA Batteries, Instruction Manual |
| Measuring Accuracy |
2% in stage 70%-100% SpO2 and meaningless when stage being smaller than 70%. 2% bpm or 2% (select larger) for Pulse Rate. |
| Measuring Performance with Weak Filling Condition |
SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is 4%, pulse rate is 2% bpm or 2% (select large) |
| Optical Sensor |
Red light (wavelength is 660nm, 6.65mW) Infrared (wavelength is 880nm, 6.75mW) |
| Power Consumption |
Smaller than 2.5 mA |
| Power Requiredments |
2 x 1.5V AAA alkaline battery, adaptable range 2.6V-3.6V |
| Pulse Intensity Display |
Columniation Display |
| Pulse Rate Measuring Range |
30 bpm - 250 bpm |
| Resistance to Surrounding Light |
The deviation between the value measured in the condition of man-made light, indoor natural light and that of a dark room is less than 1% |
| Resolution |
1% for SpO2 and 1 bpm for Pulse Rate |
| SpO2 Measuring Range |
0% - 100% |
