• Display mode: LED display
• SpO2 range:
0-100%, (resolution 1%)
accuracy: 70-100%: ± 2%, below 70% unspecified
• Measurement in weak filling condition: SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%, pulse rate error is ±2 bpm or ±2% (select larger)
• Power consumption: less than 25 mA – Voltage: DC 2.6 V – 3.6 V
• Battery working hour: two batteries can work continuously for 24 hours
