Display mode: 1.1-inch color OLED screen display
Working voltage: DC 3.0V
Display resolution: 96*64
Power consumption: no more than 30 mA
Pulse rate measurement range: 30bpm ~ 250bpm (resolution is 1bpm).
Safety type: internal power supply unit, type BF application
Battery working time: 20 hours of continuous operation, the theoretical value is 32
Resistance to ambient light interference: The measured value of blood oxygen in indoor natural light and existing illumination source is less than ±1% compared with the measured value under darkroom conditions.
Error under weak perfusion: When the pulse filling degree is 0.4%, the oximeter can correctly display the blood oxygen saturation and pulse rate values, the blood oxygen saturation error is ±4%; the pulse rate error is ±2bpm or ± 2% takes a large value
