1. integrated with spo2 probe and processing display module
2. small in volume, light in weight, easy in usage 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. low-voltage indication:
low-voltage indicator appears before working abnormally which is due to low-voltage
7. automatically power off function:
when the device is under the state of measuring interface, it will automatically power off within 8 seconds if the finger falls out of probe.
8. major applications & scope of application:
1) used to measure human hemoglobin saturation and pulse rate through finger
2) indicate the pulse intensity by the bar-display
3) suitable in family, hospital(ordinary sickroom), oxygen bar, social medical organizations
4) not suitable for use in continuous supervision for patients
5) not recommended to be used when the patient is suffering from toxicosis which caused by carbon monoxide as the problem of overrating would emerge
