Principle of the CMS50QA Pulse Oximeter is as follows: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance
Major Features
- Integrated with SpO2 probe and processing display module
- Small in volume, light in weight and convenient in carrying
- Operation of the product is simple ,low power consumption
- SpO2 value display
- Pulse rate value display, bar graph display
- A pulse rate sound indication
- With measured data overruns limits and low-voltage alarm function
- Low-voltage indication: low-voltage indicator appears before working abnormally which is due to low-voltage, and with alarm function
- Automatically power off function: when the device is under the state of measuring interface. it will automatically power off within 5
- seconds if the finger falls out of probe.
- Small appearance, more fit for children
