Fingertip Pulse Oximeter
Model: CMS50QA/QB

CMS50QA:
Major Features
1. Integrated with SpO2 probe and processing display module
2. Small in volumelight in weight and convenient in carrying
3. Operation of the product is simple, low power consumption
4. SpO2 value display
5. Pulse rate value display, bar graph display
6. A pulse rate sound indication
7. With measured data overruns limits and low-voltage alarmfunction
8. Low-voltage indication: Low-voltage indicator appears beforeworking abnormally which is due to low-voltage, and with alarmfunction
9. Automatically power off function: When the device is under thestate of measuring interface. It will automatically power offwithin 5 seconds if the finger falls out of probe.
10. Small appearance, more fit for children

Main performance
Display Mode: Segment LCD display
SpO2 Measuring Range: 0%~100%, (the resolution is 1%).
Accuracy: 70%~100%: ± 2%, Below 70% unspecified.
PR Measuring Range: 30bpm~250bpm, (the resolution is 1bpm)
Accuracy: ± 2bpm or ± 2% (select larger)
Measurement Performance in Weak Filling Condition: SpO2 and pulserate can be shown correctly when pulse-filling ratio is 0.4%. SpO2error is ± 4%, pulse rate error is ± 2 bpm or ± 2% (selectlarger).
Resistance to surrounding light: The deviation between the valuemeasured in the condition of man-made light or indoor natural lightand that of darkroom is less than ± 1%.
Power Consumption: Less than 50mA
Voltage: DC 3.6V~4.2V
Power Supply: Voltage 3.6 rechargeable lithium battery × 1
Battery working hour: 10 hours
Battery working life: Charge and discharge no less than 300times.
Safety Type: Interior Battery, BF Type
