Features

  • Achievable heart rate range of 30 – 240 beats per minute (BPM) and perfusion index (PI) range of 0.1% – 20% for a wide variety of pulse strengths and greater reliability
  • 90-dB dynamic range achievable from internal 12-bit ADC through oversampling
  • Standard display resolution of 1 BPM and 1% SpO2 for accurate vitals readings
  • Longer battery life with ultra-low (< 83 nA) shutdown current during device off-time
