Material: ABS Power Mode: Dry battery Spec.: 58mm*35mm*30mm Weight: 64g Applicable parts: Hand department Blood Oxygen Instrument 3 parameter: SPO2,PR,PI, Dual-color OLED display, 6 display modes; Low power consumption, four consecutive direction adjustable; Self-calibration value exceeds peak alarm Display Mode: 1.1-inch color OLED screen display Display resolution: 96*64 Precision: 70%~100%:±2%, less than 70% no definition Pulse Rate Measurement range: 30BPM~250BPM (resolution 1BPM) Precision: ±2BPM or ±2% large value The error of weak perfusion: When the pulse filling degree is 0.4%, the blood oxygen meter can display the blood oxygen saturation and the pulse rate value correctly, the oxygen saturation error is ±4%, the pulse rate error is ±2bpm or ±2% to take the big value. Anti-ambient light interference ability: in indoor natural daylight and the existing lighting source of blood oxygen measured values and darkroom conditions, compared to the measured value, the deviation is less than ±1% Power consumption: no more than MA Working voltage: DC 3.0V Battery: 2 knots, seventh, 1.5V alkaline battery Battery Length: Minimum working 20 hours, theoretical value of 32
