Product performance:

Display mode: 1.1 inch color OLED display

Display resolution: 96 * 64

Accuracy: 70% ～ 100%: ± 2%, less than 70% undefined

Pulse rate measurement range: 30bpm ～ 250bpm (resolution is 1bpm)

Accuracy: ± 2bpm or ± 2%, whichever is greater

Error under weak perfusion: when the pulse filling degree is 0.4%, the oximeter can correctly display the values of blood oxygen saturation and pulse rate, the error of blood oxygen saturation is ± 4%; the error of pulse rate is ± 2bpm or ± 2% Take the larger value.

Anti-interference ability of ambient light: Compared with the measurement value under dark room conditions, the measured value of blood oxygen under indoor natural light and existing illumination light source is less than ± 1%

Power consumption: no more than 30 mA

Working voltage: DC 3.0V

Battery: 2 AAA 1.5V alkaline batteries

Battery working time: minimum sustainable working for 20 hours, theoretical value is 32

Safety type: internal power supply device, BF type application part

Net weight: 50g each

Packing information: 200 / box

Each box size: 490MM * 265MM * 490MM
