Technical Parameters
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
■Low-voltage indication: low-voltage indicator appears before working abnormally which is due to low-voltage
■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
Main performance
Display Mode: Segment LCD display
SpO2 Measuring Range: 0%～100%, (the resolution is 1%).
Accuracy: 70%～100%: ±2% ,Below 70% unspecified.
