Contec Pulse Oximeter CMS50Q1

• SpO2 value display
• Pulse rate value display, bar graph display 
• Pulse waveform display
• The display mode can be changed
• Screen brightness can be changed
• 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
