Pulse oximeter AH-50B
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
